abstract = {The quantum revolution of the 20th century culminated in the development of quantum optics and the study of nonclassical light. By the beginning of this century, scientific laboratories could produce and handle various quantum states of light: from single photons and photon pairs to squeezed states and bright twin beams. Gradually, this toolbox has become part of a range of emerging quantum technologies. The first real application of quantum optics was quantum key distribution,1 commercialized almost two decades ago. This is not surprising because photons are the ideal messengers and very convenient for communications as they can make use of existing optical fiber network infrastructure. A major milestone for quantum sensing is its application to new disciplines: this has excitingly been showcased by the next-generation of gravitational-wave detectors that employ squeezed light to enhance detector sensitivity;2,3 we anticipate other achievements will follow and span a huge range of disciplines, from fundamental physics to biomedicine and more. This special topic collection samples key research areas from the wider literature on quantum imaging, sensing, and spectroscopy. It also showcases developments in enabling technologies including novel nonlinear light sources as well as the growing use of enhanced CCD cameras for quantum imaging.},

volume = {116},
abstract = {On September 14, 2015 at 09:50:45 UTC the two detectors of the Laser
Interferometer Gravitational-Wave Observatory simultaneously observed
a transient gravitational-wave signal. The signal sweeps upwards
in frequency from 35 to 250 Hz with a peak gravitational-wave strain
of 1.0x10-21. It matches the waveform predicted by general relativity
for the inspiral and merger of a pair of black holes and the ringdown
of the resulting single black hole. The signal was observed with
a matched-filter signal-to-noise ratio of 24 and a false alarm rate
estimated to be less than 1 event per 203000 years, equivalent to
a significance greater than 5.1sigma. The source lies at a luminosity
distance of 410+160-180??Mpc corresponding to a redshift z=0.09+0.03-0.04.In
the source frame, the initial black hole masses are 36+5-4Msolar
and 29+4-4Msolar, and the final black hole mass is 62+4-4Msolar,
with 3.0+0.5-0.5Msolarc2 radiated in gravitational waves. All uncertainties
define 90% credible intervals. These observations demonstrate the
existence of binary stellar-mass black hole systems. This is the
first direct detection of gravitational waves and the first observation
of a binary black hole merger.},

modes at threshold of a random laser are in direct correspondence

is well known in conventional lasers but not known until recently
for random lasers. This paper presents numerical results of the multimode
regime that takes place when the pumping rate is progressively increased
above threshold. Behavior that is already known in standard lasers,
such as mode competition and nonlinear wave mixing, are shown to
also take place in random lasers thus reinforcing their recent modal
description. However, due to the complexity of the laser modes and
to the openness of such lasers, which require large external pumping
to compensate for strong loss, one observes that these effects are
systematic and can be more pronounced than in a conventional laser.},

a mean-field spin-glass-like model. The model is solved by the replica
method, and replica-symmetry breaking phase transition is predicted.
The transition describes a mode-locking process in which the phases
of the modes are locked to random (history and sample-dependent)
values. An extended discussion of possible experimental implications

abstract = {A laser is not necessarily a sophisticated device: pumping an amplifying
medium randomly filled with scatterers makes a perfectly viable ‘random
laser’. The absence of mirrors greatly simplifies laser design, but
control over the emission wavelength and directionality is lost,
seriously hindering prospects1, 2, 3, 4 for this otherwise simple
laser. Recently, we proposed an approach to tame random lasers5,
inspired by coherent light control in complex media6. Here, we implement
this method in an optofluidic random laser7 where modes are spatially
extended and overlap, making individual mode selection impossible,
a priori. We show experimentally that control over laser emission
can be regained even in this extreme case. By actively shaping the
optical pump within the random laser, single-mode operation at any
selected wavelength is achieved with spectral selectivity down to
0.06 nm and more than 10 dB side-lobe rejection. This method paves
the way towards versatile tunable and controlled random lasers as
well as the taming of other laser sources.},

We discuss the case of states in the whole Bloch sphere as well as
the restricted situation where these states are known to lie on the
equatorial plane. For the former case we obtain that the optimal
measurement does not depend on the prior probability distribution
provided it is isotropic. Although the equatorial-plane case does
not have this property for arbitrary N, we give a prior-independent
scheme which becomes optimal in the asymptotic limit of large N.
We compute the maximum mean fidelity in this asymptotic regime for
the two cases. We show that within the pointwise estimation approach
these limits can be obtained in a rather easy and rapid way. This
derivation is based on heuristic arguments that are made rigorous
by using van Trees inequalities. The interrelation between the estimation
of the purity and the direction of the state is also discussed. In
the general case we show that they correspond to independent estimations

naturally in stellar gases2–4 and planetary atmospheres5,6. The possibility
of additional scattering-induced feedback4,7-random lasing8–14-could
explain the unusual properties of some space masers15. Here, we report
experimental evidence of random lasing in a controlled, cold atomic
vapour, taking advantage of Raman gain. By tuning the gain frequency
in the vicinity of a scattering resonance, we observe an enhancement
of the light emission due to random lasing. The unique possibility
to both control the experimental parameters and to model the microscopic
response of our system provides an ideal test bench for better understanding
natural lasing sources, in particular the role of resonant scattering
feedback in astrophysical lasers. A cloud of cold atoms constitutes
a new medium},

Photon-count distribution measurements indicate that, to a high degree
of accuracy, the field amplitude of the scattered light fluctuates
as a log-normal variate. The irradiance correlation function is a
gaussian function of time with a half-width at half-height that varies
inversely with the angular speed of the ground glass but is largely
independent of the angle of scattering. Identical functional dependence
was previously found, using a ground glass with much smaller surface
inhomogeneities (average size 1 gim). Finally, we report some experimental
tests of a recent calculation by Mitchell concerning what has been
defined as the permanence of the log-normal distribution. We find
that, even when the detecting surface of the photomultiplier is illuminated
by several coherence areas of the scattered field during a single
counting interval, the field-amplitude distribution remains log-normal
to an excellent approximation.},

month = {March},
pages = {267-270},

abstract = {Photon beams exhibit temporal correlations that are characteristics
of their emission mechanism. For instance, photons issued from incoherent
sources tend to be detected in bunches. This striking 'bunching'
behaviour has been observed in the seminal experiment by Hanbury-Brown
and Twiss (HBT) in the fifties, who measured the time of arrival
of partially coherent photons on two separate photon-counting modules1.
Since then, HBT interferometry has become a widespread technique
to study photon correlations down to only the nanosecond range, because
of the detector-limited bandwidth, preventing the observation of
bunching for real thermal sources. It has been suggested later that
two-photon absorption (TPA) could measure the photon temporal correlations
at a much shorter timescale2, 3, as it involves an almost simultaneous
absorption of two photons, within a maximum delay given by the Heisenberg
principle. Here, for the first time, this prediction is experimentally
demonstrated using TPA in a GaAs photon-counting module. We have
observed photon bunching in the femtosecond range for real blackbody
sources (an enhancement of six orders of magnitude in the time resolution
of present techniques), opening the way to monitor optical quantum
statistics at the ultrashort timescale.},

title = {A Novel Type of Very Long Baseline Astronomical Intensity Interferometer},
year = {2013},
pages = {1096-1101},
volume = {436},
abstract = {This article presents a novel type of very long baseline astronomical
interferometer that uses the fluctuations, as a function of time,
of the intensity measured by a quadratic detector, which is a common
type of astronomical detector. The theory on which the technique
is based is validated by laboratory experiments. Its outstanding
principal advantages comes from the fact that the angular structure
of an astronomical object is simply determined from the visibility
of the minima of the spectrum of the intensity fluctuations measured
by the detector, as a function of the frequency of the fluctuations,
while keeping the spacing between mirrors constant. This would allow
a simple setup capable of high angular resolutions because it could
use an extremely large baseline. Another major interest is that it
allows for a more efficient use of telescope time because observations
at a single baseline are sufficient, while amplitude and intensity
interferometers need several observations at different baselines.
The fact that one does not have to move the telescopes would also
allow detecting faster time variations because having to move the
telescopes sets a lower limit to the time variations that can be
detected. The technique uses wave interaction effects and thus has
some characteristics in common with intensity interferometry. A disadvantage
of the technique, like in intensity interferometry, is that it needs
strong sources if observing at high frequencies (e.g. the visible).
This is a minor disadvantage in the radio region. At high frequencies,
this disadvantage is mitigated by the fact that, like in intensity
interferometry, the requirements of the optical quality of the mirrors
used are far less severe than in amplitude interferometry so that
poor quality large reflectors (e.g. Cherenkov telescopes) can be
used in the optical region.},

the angular size of stars can be measured by correlating the intensity
fluctuations measured by two detectors at two different locations.
Since then, non-local correlation measurements have become ubiquitous
in many areas of physics and have also been applied, beyond photons,
to electrons, matter waves and subatomic particles. An important
assumption in HBT interferometry is that the particles do not interact
on their way from the source to the detectors. However, this assumption
is not always valid. Here, we study the effects of interactions on
HBT interferometry by considering the propagation of light fields
in a nonlinear medium that induces interactions between the photons.
We show that interactions affect multipath interference, limiting
the ability to extract information on the source. Nevertheless, we
find that proper analysis of the intensity fluctuations can recover
the size of the source, even in the presence of interactions.},

system of resonant scatterers pumped by an external laser. The eigenmodes
of the finite system (quasistates) are “lossy” in the absence of

characterized by their decay rates. Lasing occurs when the gain compensates
the decay rate of the quasistate with the longest lifetime. The dependence
of the lasing threshold on the number of scatterers (size of the
system) is found to be I propto 1/sqrtN, which agrees with recent
experiments. We demonstrate that this dependence is strongly related
to the fluctuations of quasistate decay rates and discuss the nature
of these fluctuations.},

robust for colored noise, whereas this is not the case for white

abstract = {Intensity Interferometry is a technique for the calculation of stars
angular diameters that could in principle overcome some major disadvantages
of traditional amplitude interferometry. This technique was first
applied in 1956 by Hanbury-Brown and Twiss (HBT) in Narrabri (Australia),
when they measured the diameter of several bright blue stars. Since
then, the HBT technique nearly disappeared from astrophysics. Nowadays
theory and technology are mature enough to guarantee a renewed exploitation
of this effect in astronomy. Our group in Padua has built Iqueye,
a high speed astronomical photon counting device, first tested at
the ESO 3.5m New Technology Telescope (La Silla, Chile) in January
2009. With the collected data, a posteriori we perform the calculation
of g2(x,0) as a first step to verify the zero-baseline correlation
coefficient in a HBT intensity interferometer. In a similar way,
g2(0,t) could be calculated. To perform such calculations, a dedicated
software correlator has been designed, implemented and optimized
and will be described in depth in the present paper. Although the
size of the NTT does not allow an acceptable signal to noise ratio
for calculating second order effects, our experiments demonstrate
the value of an Iqueye-like instrument for HBT like experiments.
Hopefully an improved version of IQuEye applied to larger telescopes,
like the four 8m VLTs and even to the future 42m Extremely Large
Telescope will be the perfect instrument for a novel exploitation
of the photon stream from celestial objects.},

conceptual foundations of quantum mechanics. The theorem shows that
essentially all local theories of natural phenomena that are formulated
within the framework of realism may be tested using a single experimental
arrangement. Moreover, the predictions by those theories must significantly
differ from those by quantum mechanics. Experimental results evidently
refute the theorem's predictions for these theories and favour those
of quantum mechanics. The conclusions are philosophically startling:
either one must totally abandon the realistic philosophy of most
working scientists, or dramatically revise out concept of space-time.},

equatorial-debris puzzle, which is crucial regarding the nature of
this star and its instability. Moreover, the observed bright narrow

All existing cameras and all spectrometers measure aspects of the

light has additional degrees of freedom, manifest in the statistics
of photon arrival times, or in the amount of photon orbital angular
momentum. Such quantum-optical measures may carry information on
how the light was created at the source, and whether it reached the
observer directly or via some intermediate process. Astronomical
quantum optics may help to clarify emission processes in natural
laser sources and in the environments of compact objects, while high-speed
photoncounting with digital signal handling enables multi-element
and long-baseline versions of the intensity interferometer. Time
resolutions of nanoseconds are required, as are large photon fluxes,
making photonic astronomy very timely in an era of large telescopes.

abstract = {Natural laser emission may be produced whenever suitable atomic energy
levels become overpopulated. Strong evidence for laser emission exists
in astronomical sources such as Eta Carinae, and other luminous stars.
However, the evidence is indirect in that the laser lines have not
yet been spectrally resolved. The lines are theoretically estimated
to be extremely narrow, requiring spectral resolutions very much
higher (R near 108) than possible with ordinary spectroscopy. Such
can be attained with photon-correlation spectroscopy on nanosecond
timescales, measuring the autocorrelation function of photon arrival
times to obtain the coherence time of light, and thus the spectral
linewidth. A particular advantage is the insensitivity to spectral,
spatial, and temporal shifts of emission-line components due to local
velocities and probable variability of ‘hot-spots’ in the source.
A laboratory experiment has been set up, simulating telescopic observations
of cosmic laser emission. Numerically simulated observations estimate
how laser emission components within realistic spectral and spatial
passbands for various candidate sources carry over to observable
statistical functions. The Universe is revealed as an ever-changing
entity, filled with the energy flowing from stars and galaxies. While
astronomy covers a diverse range of astrophysical objects and timescales,
the emerging field of high time resolution astrophysics (HTRA) focuses
on the outermost dynamic limits presented by the Universe. On these
extreme timescales, the Universe is still largely unexplored, and
the questions posed by this developing field have lead to the beginning
of a new scientific quest for answers. The conference “Universe at
sub-second timescales” brought together leading astronomers and astrophysicists,
who have so far developed HTRA independently, with the goal of reviewing
the current state of the art of HTRA, exploring the questions posed,
and to discuss where we should go from here.},

abstract = {A long-held astronomical vision is to realize diffraction-limited
optical aperture synthesis over kilometer baselines. This will enable
imaging of stellar surfaces and their environments, show their evolution
over time, and reveal interactions of stellar winds and gas flows
in binary star systems. An opportunity is now opening up with the
large telescope arrays primarily erected for measuring Cherenkov
light in air induced by gamma rays. With suitable software, such
telescopes could be electronically connected and used also for intensity
interferometry. With no optical connection between the telescopes,
the error budget is set by the electronic time resolution of a few
nanoseconds. Corresponding light-travel distances are on the order
of one meter, making the method practically insensitive to atmospheric
turbulence or optical imperfections, permitting both very long baselines
and observing at short optical wavelengths. Theoretical modeling
has shown how stellar surface images can be retrieved from such observations
and here we report on experimental simulations. In an optical laboratory,
artificial stars (single and double, round and elliptic) are observed
by an array of telescopes. Using high-speed photon-counting solid-state
detectors and real-time electronics, intensity fluctuations are cross
correlated between up to a hundred baselines between pairs of telescopes,
producing maps of the second-order spatial coherence across the interferometric
Fourier-transform plane. These experiments serve to verify the concepts
and to optimize the instrumentation and observing procedures for
future observations with (in particular) CTA, the Cherenkov Telescope
Array, aiming at order-of-magnitude improvements of the angular resolution
in optical astronomy.},

In observing stars, current capabilities are only marginal in beginning
to image the disks of a few, although many stars will appear as surface
objects for baselines of hundreds of meters. Since atmospheric turbulence
makes ground-based phase interferometry challenging for such long
baselines, kilometric space telescope clusters have been proposed
for imaging stellar surface details. The realization of such projects
remains uncertain, but comparable imaging could be realized by ground-based
intensity interferometry. While insensitive to atmospheric turbulence
and imperfections in telescope optics, the method requires large
flux collectors, such as being set up as arrays of atmospheric Cherenkov
telescopes for studying energetic gamma rays. High-speed detectors
and digital signal handling enable very many baselines to be synthesized
between pairs of telescopes, while stars may be tracked across the
sky by electronic time delays. First observations with digitally
combined optical instruments have now been made with pairs of 12-meter
telescopes of the VERITAS array in Arizona. Observing at short wavelengths
adds no problems, and similar techniques on an extremely large telescope
could achieve diffraction-limited imaging down to the atmospheric
cutoff, achieving a spatial resolution significantly superior by
that feasible by adaptive optics operating in the red or near-infrared.},

abstract = {With its unprecedented light-collecting area for night-sky observations,
the Cherenkov Telescope Array (CTA) holds great potential for also
optical stellar astronomy, in particular as a multi-element intensity
interferometer for realizing imaging with sub-milliarcsecond angular
resolution. Such an order-of-magnitude increase of the spatial resolution
achieved in optical astronomy will reveal the surfaces of rotationally
flattened stars with structures in their circumstellar disks and
winds, or the gas flows between close binaries. Image reconstruction
is feasible from the second-order coherence of light, measured as
the temporal correlations of arrival times between photons recorded
in different telescopes. This technique (once pioneered by Hanbury
Brown and Twiss) connects telescopes only with electronic signals
and is practically insensitive to atmospheric turbulence and to imperfections
in telescope optics. Detector and telescope requirements are very
similar to those for imaging air Cherenkov observatories, the main
difference being the signal processing (calculating cross correlations
between single camera pixels in pairs of telescopes). Observations
of brighter stars are not limited by sky brightness, permitting efficient
CTA use during also bright-Moon periods. While other concepts have
been proposed to realize kilometerscale optical interferometers of
conventional amplitude (phase-) type, both in space and on the ground,
their complexity places them much further into the future than CTA,
which thus could become the first kilometer-scale optical imager
in astronomy.},

All emission lines in our observed wavelength interval (5200-6000

behavior of the excess emission in the C III lambda5696 line can
be related to the wind-wind collision phenomenon. Varying features
of Stokes q and u are seen across the strong lines, probably as a
result of variable electron scattering of mainly continuum light.
The spherical symmetry of the WR wind is thus broken by the presence
of the O companion and clumping in the WR wind. Similar features
in the extended red wing of the C III lambda5696 emission line remain
unexplained. No obvious circular line polarization features are seen
across any emission line above the 3 sigma~0.03% instrumental level.},

abstract = {Most observational techniques in astronomy can be understood as exploiting
the various forms of the rst-order correlation function g(1). As
however demonstrated by the Narrabri Stellar Intensity Interferometer
back in the 1960's by Hanbury Brown & Twiss, and which is the rst
experiment to measure the second-order correlation function g(2),
light can carry more information than simply its intensity, spectrum
and polarization. Since this experiment, theoretical and laboratory
studies of non-classical properties of light have become a very active eld
of research, namely quantum optics. Despite the variety of results
in this eld, astrophysics remained focused essentially on rst-order
coherence. In this paper, we study the possibility that quantum properties
of light could be observed in cosmic sources. We provide the basic
mathematical ingredients about the rst and the second order correlation
functions, applied to the modern context of astronomical observations.
We aim at replacing the Hanbury Brown & Twiss experiment in this
context, and present two fundamental limitations of an intensity
interferometer: the requirement of a chaotic light source, and the
rapid decreases of the amount of correlated uctuations with surface's
temperature. The rst of these limitations emphasize paradoxically
the fact that the exploitation of g(2) is richer than what a modern
intensity interferometer could bring and is particularly interesting
for sources of non-thermal light. We also discuss new photon-counting
avalanche photodiodes currently being developed in Grenoble, and
their the impact on limiting magnitudes of an intensity interferometer.
We conclude by brie y presenting why microquasars in our galaxy and
their extragalactic parents can represent an excellent rst},

abstract = {The Optical Search for Extraterrestrial Intelligence (OSETI) attempts
to detect collimated, narrowband pulses of electromagnetic radiation.
These pulses may either consist of signals intentionally directed
at the Earth, or signals between two star systems with a vector that
unintentionally intersects the Solar System, allowing Earth to intercept
the communication. But should we expect to be able to intercept these
unintentional signals? And what constraints can we place upon the
frequency of intelligent civilisations if we do? We carry out Monte
Carlo Realisation simulations of interstellar communications between
civilisations in the Galactic Habitable Zone (GHZ) using collimated
beams. We measure the frequency with which beams between two stars
are intercepted by a third. The interception rate increases linearly
with the fraction of communicating civilisations, and as the cube
of the beam opening angle, which is somewhat stronger than theoretical
expectations, which we argue is due to the geometry of the GHZ. We
find that for an annular GHZ containing 10,000 civilisations, intersections
are unlikely unless the beams are relatively uncollimated. These
results indicate that optical SETI is more likely to find signals
deliberately directed at the Earth than accidentally intercepting
collimated communications. Equally, civilisations wishing to establish
a network of communicating species may use weakly collimated beams
to build up the network through interception, if they are willing
to pay a cost penalty that is lower than that meted by fully isotropic
beacons. Future SETI searches should consider the possibility that
communicating civilisations will attempt to strike a balance between
optimising costs and encouraging contact between civilisations, and
look for weakly collimated pulses as well as narrow-beam pulses directed
deliberately at the Earth.},

optical beams, including squeezed states of light, at audio-band
frequencies. Current designs of advanced gravitational wave interferometers
use some type of homodyne readout for signal detection, in part because
of its compatibility with the use of squeezed light. The readout
scheme used in Advanced LIGO, called DC readout, is however not a
balanced detection scheme. Instead, the local oscillator field, generated
from a dark fringe offset, co-propagates with the signal field at
the anti-symmetric output of the beam splitter. This article examines
the alternative of a true balanced homodyne detection for the readout
of gravitational wave detectors such as Advanced LIGO. Several practical
advantages of the balanced detection scheme are described.},

abstract = {The explosive fate of massive Wolf–Rayet stars1 (WRSs) is a key open
question in stellar physics. An appealing option is that hydrogen-deficient
WRSs are the progenitors of some hydrogen-poor supernova explosions
of types IIb, Ib and Ic (ref. 2). A blue object, having luminosity
and colours consistent with those of some WRSs, has recently been
identified in pre-explosion images at the location of a supernova
of type Ib (ref. 3), but has not yet been conclusively determined
to have been the progenitor. Similar work has so far only resulted
in non-detections4. Comparison of early photometric observations
of type Ic supernovae with theoretical models suggests that the progenitor
stars had radii of less than 1012 centimetres, as expected for some
WRSs5. The signature of WRSs, their emission line spectra, cannot
be probed by such studies. Here we report the detection of strong
emission lines in a spectrum of type IIb supernova 2013cu (iPTF13ast)
obtained approximately 15.5 hours after explosion (by ‘flash spectroscopy’,
which captures the effects of the supernova explosion shock breakout
flash on material surrounding the progenitor star). We identify Wolf–Rayet-like
wind signatures, suggesting a progenitor of the WN(h) subclass (those
WRSs with winds dominated by helium and nitrogen, with traces of
hydrogen). The extent of this dense wind may indicate increased mass
loss from the progenitor shortly before its explosion, consistent
with recent theoretical predictions.},

year = {2012},

pages = {7},
volume = {548},
abstract = {Context. We observed the Crab pulsar in October 2008 at the Copernico
Telescope in Asiago – Cima Ekar with the optical photon counter Aqueye
(the Asiago Quantum Eye) which has the best temporal resolution and
accuracy ever achieved in the optical domain (hundreds of picoseconds).
Aims. Our goal was to perform a detailed analysis of the optical
period and phase drift of the main peak of the Crab pulsar and compare
it with the Jodrell Bank ephemerides. Methods. We determined the
position of the main peak using the steepest zero of the cross-correlation
function between the pulsar signal and an accurate optical template.
Results. The pulsar rotational period and period derivative have
been measured with great accuracy using observations covering only
a 2 day time interval. The error on the period is 1.7 ps, limited
only by the statistical uncertainty. Both the rotational frequency
and its first derivative are in agreement with those from the Jodrell
Bank radio ephemerides archive. We also found evidence of the optical
peak leading the radio one by ~230µs. The distribution of phase-residuals
of the whole dataset is slightly wider than that of a synthetic signal
generated as a sequence of pulses distributed in time with the probability
proportional to the pulse shape, such as the average count rate and
background level are those of the Crab pulsar observed with Aqueye.
Conclusions. The counting statistics and quality of the data allowed
us to determine the pulsar period and period derivative with great
accuracy in 2 days only. The time of arrival of the optical peak
of the Crab pulsar leads the radio one in agreement with what recently
reported in the literature. The distribution of the phase residuals
can be approximated with a Gaussian and is consistent with being
completely caused by photon noise (for the best data sets).},

As a practical application, we focus on certain one-parameter classes

realization of the original GHZ argument and which result from imperfect
preparations of the pure GHZ state. In these cases we determine for
which values of the parameter controlling the noise a nonlocality

abstract = {The refractive index and its variation with temperature, the thermo-optic
coefficient (d n/dT), are analyzed with two separate physically meaningful
models for more than a dozen of some important Schott and Ohara optical
glasses to find the refractive index at any operating temperature
for any wavelength throughout the transmission region. The room-temperature
catalog values of refractive indices are fitted with a two-pole Sellmeier
equation. Both the average electronic absorption band gap and the
lattice absorption frequency, lying in the vacuum UV and IR regions,
respectively, contribute to the refractive indices and their dispersion.
The estimated absorption band gaps are at 8.5-11.9 eV, and these
values agree with the measured values at 8.8-11.6 eV satisfactorily
for normal optical glasses. The higher-index glasses have electronic
absorption in the region of 5.6-6.3 eV, and the estimated band gap
of SF6 glass is 6.0 eV. The dispersion of thermo-optic coefficients
is accounted for satisfactorily with a model, based on three physical
parameters, the thermal expansion coefficient and excitonic and isentropic
optical band gaps that are in the vacuum UV region. These optical
constants are used to compute refractive indices at any operating
temperature and wavelength. The Abbé number and the chromatic dispersion
characteristics of these glasses are evaluated from the computed
optical constants; the values of the chromatic dispersions are evaluated
particularly at the three optical windows of the optical fiber communication
systems and femtosecond technology.},

scattering replaces the standard optical cavity of traditional lasers

shaped or polydisperse scatterers, with a certain average scattering
strength that was constant over the frequency window of the laser2,
3, 4. In this letter we consider the case where the scattering is
resonant. We demonstrate that randomly assembled monodisperse spheres
can sustain scattering resonances over the gain frequency window,
and that the lasing wavelength can therefore be controlled by means
of the diameter and refractive index of the spheres. The system is
therefore a random laser with an a priori designed lasing peak within
the gain curve.},

abstract = {We report on an attempt to accurately wavelength calibrate four nights
of data taken with the Keck HIRES spectrograph on QSO PHL957, for
the purpose of determining whether the fine structure constant was
different in the past. Using new software and techniques, we measured
the redshifts of various Ni II, Fe II, Si II, etc. lines in a damped
Ly alpha system at z = 2.309. Roughly half the data were taken through
the Keck iodine cell which contains thousands of well calibrated
iodine lines. Using these iodine exposures to calibrate the normal
Th-Ar Keck data pipeline output we found absolute wavelength offsets
of 500 m/s to 1000 m/s with drifts of more than 500 m/s over a single
night, and drifts of nearly 2000 m/s over several nights. These offsets
correspond to an absolute redshift of uncertainty of about deltaz
approx 10-5 (delta wavelength approx 0.02 angstroms), with daily
drifts of around deltaz approx 5 x 10-6 (delta wavelength approx
0.01angstroms), and multiday drifts of nearly delta z approx 2 x
10-5 (angstroms 0.04 angstroms). The causes of the wavelength offsets
are not known, but since claimed shifts in the fine structure constant
would result in velocity shifts of less than 100 m/s, this level
of systematic uncertainty may make it difficult to use Keck HIRES
data to constrain the change in the fine structure constant. Using
our calibrated data, we applied both our own fitting software and
standard fitting software to measure delta alpha / alpha , but discovered
that we could obtain results ranging from significant detection of
either sign, to strong null limits, depending upon which sets of
lines and which fitting method was used. We thus speculate that the
discrepant results on delta alpha / alpha reported in the literature
may be due to random fluctuations coming from under-estimated systematic
errors in wavelength calibration and fitting procedure.},

width and strength of the variable Halpha emission component are
consistent with the hypothesized dMe companion proposed to explain
the hard X-ray emission. A dMe companion, however, cannot explain
the possible detection of variable He II and [N II] emission. Follow-up
spectroscopic monitoring of the Helix Nebula central star is needed
to better establish the identification of the spectral lines and
their temporal behavior in order to determine the origin of the optical

abstract = {Eta Carinae’s inner ejecta are dominated observationally by the bright
Weigelt blobs and their famously rich spectra of nebular emission
and absorption lines. They are dense (ne 107 to 108 cm-3), warm (Te
6000 to 7000 K) and slow moving (40 km s-1) condensations of mostly
neutral (H0) gas. Located within 1000 AU of the central star, they
contain heavily CNO-processed material that was ejected from the
star about a century ago. Outside the blobs, the inner ejecta include
absorption-line clouds with similar conditions, plus emission-line
gas that has generally lower densities and a wider range of speeds
(reaching a few hundred km s-1) compared to the blobs. The blobs
appear to contain a negligible amount of dust and have a nearly dust-free
view of the central source, but our view across the inner ejecta
is severely affected by uncertain amounts of dust having a patchy
distribution in the foreground. Emission lines from the inner ejecta
are powered by photoionization and fluorescent processes. The variable
nature of this emission, occurring in a 5.54 yr “event” cycle, requires
specific changes to the incident flux that hold important clues to
the nature of the central object.},

abstract = {It is shown by a quantum-mechanical treatment that the emission times
of photoelectrons at different points illuminated by a plane wave
of light are partially correlated, and identical results are obtained
by a classical theory in which the photocathode is regarded as a
squarelaw detector of suitable conversion efficiency. It is argued
that the phenomenon exemplifies the wave rather than the particle
aspect of light and that it may most easily be interpreted as a correlation
between the intensity fluctuations at different points on a wavefront
which arise because of interference between different frequency components
of the light. From the point of view of the corpuscular picture the
interpretation is much less straight-forward but it is shown that
the correlation is directly related to the so-called bunching of
photons which arises because light quanta are mutually indistinguishable
and obey Bose-Einstein statistics. However, it is stressed that the
use of the photon concept before the light energy is actually detected
is highly misleading since, in an interference experiment, the electromagnetic
field behaves in a manner which cannot be explained in terms of classical
particles. The quantitative predictions of the theory have been confirmed
by laboratory experiments and the phenomenon has been used, in an
interferometer, to measure the apparent angular diameter of Sirius:
these results, together with further applications to astronomy, will
be discussed in detail in later papers. It is shown that the classical
and quantum treatments give identical results when applied to find
the fluctuations in the photoemission current produced by a single
light beam, and the connexion between these fluctuations and the
correlation between photons in coherent beams is pointed out. The
results given here are in full agreement with those obtained by Kahn
from an analysis based on quantum statistics: however, they differ
from those derived on thermodynamical grounds by Fellgett and by
Clark Jones and the reasons for this discrepancy are discussed.},

two radio signals are therefore lost, and only the correlation in
their intensity fluctuations is measured; so that the principle differs
radically from that of the familiar Michelson interferometer where
the signals are combined before detection and where their relative
phase must be preserved. This new system was developed for use with
vey long baselines, and experimentally it has proved to be largely
free of the effects of ionospheric scintillation2. These advantages
led us to suggest1 that the principle might be applied to the measurement
of the angular diameter of visual stars. Thus one could replace the
two aerials by two mirrors M1, M2 (Fig.lb), and the radiofrequency
detectors by photoelectric-cells C1 C2, and measure, as a function
of the separation of the mirrors, the correlation between the fluctuations
in the currents from the cells when illuminated by a star.},

be reproduced by a local realist theory. That conflict is expressed
by Bell's inequality, which is usually derived under the assumption
that there are no statistical correlations between the choices of
measurement settings and anything else that can causally affect the
measurement outcomes. In previous experiments, this "freedom of choice"
was addressed by ensuring that selection of measurement settings
via conventional "quantum random number generators" (QRNGs) was spacelike
separated from the entangled particle creation. This, however, left
open the possibility that an unknown cause affected both the setting
choices and measurement outcomes as recently as mere microseconds
before each experimental trial. Here we report on a new experimental
test of Bell's inequality that, for the first time, uses distant
astronomical sources as "cosmic setting generators." In our tests
with polarization-entangled photons, measurement settings were chosen
using real-time observations of Milky Way stars while simultaneously
ensuring locality. We observe statistically significant >11.7sigma
and >13.8sigma violations of Bell's inequality with estimated p-values
of <7.4x10e-32 and <1.1x10e-43, respectively, thereby pushing back
by approximately 600 years the most recent time by which any local

emission lines of hydrogen, helium, and nitrogen are associable with
other spatial structures at other velocities within the Homunculus,
no emission lines from these elements correspond to the spatial structure

emission line requires an ionization or excitation energy above approximately
8 eV. Ionized gas extends spatially along the aperture, oriented
along the polar axis of the Homunculus, and in velocity around the

year = {1974},
pages = {30-31},
volume = {248},
abstract = {Quantum gravitational effects are usually ignored in calculations
of the formation and evolution of black holes. The justification
for this is that the radius of curvature of space-time outside the
event horizon is very large compared to the Planck length (Ghbar/c3)1/2
~ 10-33 cm, the length scale on which quantum fluctuations of the
metric are expected to be of order unity. This means that the energy
density of particles created by the gravitational field is small
compared to the space-time curvature. Even though quantum effects
may be small locally, they may still, however, add up to produce
a significant effect over the lifetime of the Universe ~ 1017 s which
is very long compared to the Planck time ~ 10-43 s. The purpose of
this letter is to show that this indeed may be the case: it seems
that any black hole will create and emit particles such as neutrinos
or photons at just the rate that one would expect if the black hole
was a body with a temperature of (kappa/2pi) (hbar/2k) ~ 10-6 (Msolar/M)K
where kappa is the surface gravity of the black hole1. As a black
hole emits this thermal radiation one would expect it to lose mass.
This in turn would increase the surface gravity and so increase the
rate of emission. The black hole would therefore have a finite life
of the order of 1071 (Msolar/M)-3 s. For a black hole of solar mass
this is much longer than the age of the Universe. There might, however,
be much smaller black holes which were formed by fluctuations in
the early Universe2. Any such black hole of mass less than 1015 g
would have evaporated by now. Near the end of its life the rate of
emission would be very high and about 1030 erg would be released
in the last 0.1 s. This is a fairly small explosion by astronomical
standards but it is equivalent to about 1 million 1 Mton hydrogen
bombs.},

of the very small and the very large. They are predicted by some
unified theories of particle interactions. If they exist, they may
help to explain some of the largest-scale structures seen in the
Universe today. They are `topological defects' that may have been
formed at phase transitions in the very early history of the Universe,
analogous to those found in some condensed-matter systems --- vortex
lines in liquid helium, flux tubes in type-II superconductors, or
disclination lines in liquid crystals. In this review, we describe
what they are, why they have been hypothesized and what their cosmological
implications would be. The relevant background from the standard
models of particle physics and cosmology is described in section
1. In section 2, we review the idea of symmetry breaking in field
theories, and show how the defects formed are constrained by the
topology of the manifold of degenerate vacuum states. We also discuss
the different types of cosmic strings that can appear in different
field theories. Section 3 is devoted to the dynamics of cosmic strings,
and section 4 to their interaction with other fields. The formation
and evolution of cosmic strings in the early Universe is the subject
of section 5, while section 6 deals with their observational implications.
Finally, the present status of the theory is reviewed in section
7.},

$21$ H$_2$O maser sources in the vicinity of ultracompact (UC) HII
regions. This survey provides the basis for future studies with milli–arcsecond
resolution, utilizing very long baseline interferometry (VLBI) techniques.
Emission from the $6_{16}-5_{23}$ masing transition of interstellar
H$_2$O is observed in the close vicinity of UC HII regions with a
median angular distance of $2\hbox{$.\!\!^{\prime\prime}$}9$ and
a median linear projected distance of $0.1\,$pc from the continuum
peak. We find that for UC HII regions with cometary morphology the
water maser emission is located in front of the cometary arc whereas
for non-cometary UC HII regions the water masers are often observed
projected onto the contours of the ionized gas. Due to the large
median distance of the water masers from the I-front of the UC HII
region, it is unlikely, that the water masers are formed in the shocked
layer of warm molecular gas in the interface between the ionized
gas of the UC HII region and surrounding molecular gas which is predicted
by the Bow Shock theory of UC HII regions. A comparison with maps
in the NH$_3$ inversion transitions shows that in at least 7 cases,
the water masers are associated with hot ($T$ $ > 100\,$K), dense
($n$(H${_2}) \approx 10^{7}\,$cm$^{-3}$) molecular clumps. For the
UC HII regions G5.89-0.38 and G45.07+0.13 we find spatial and velocity
correspondence between water masers and outflowing molecular gas.
It is thus likely, that for these sources the H$_2$O masers are taking
part in the bipolar outflow. A survey of water maser emission toward

abstract = {Random lasers are a developing class of light sources that utilize
a highly disordered gain medium as opposed to a conventional optical
cavity. Although traditional random lasers often have a relatively
broad emission spectrum, a random laser that utilizes vibration transitions
via Raman scattering allows for an extremely narrow bandwidth, on
the order of 10 cm-1Here we demonstrate the first experimental evidence
of lasing via a Raman interaction in a bulk three-dimensional random
medium, with conversion efficiencies on the order of a few percent.
Furthermore, Monte Carlo simulations are used to study the complex
spatial and temporal dynamics of nonlinear processes in turbid media.
In addition to providing a large signal, characteristic of the Raman
medium, the random Raman laser offers us an entirely new tool for
studying the dynamics of gain in a turbid medium.},

abstract = {A method of image recovery using noniterative phase retrieval is proposed
and investigated by simulation. This method adapts the Cauchy-Riemann
equations to evaluate derivatives of phase based on derivatives of
magnitude. The noise sensitivity of the approach is reduced by employing
a least-mean-squares fit. This method uses the analytic properties
of the Fourier transform of an object, the magnitude of which is
measured with an intensity interferometer. The solution exhibits
the degree of nonuniqueness expected from root-flipping arguments
for the one-dimensional case, but a simple assumption that restricts
translational ambiguity also restricts the space of solutions and
permits essentially perfect reconstructions for a number of non-symmetric
one-dimensional objects of interest. Very good reconstructions are
obtained for a large fraction of random objects, within an overall
image flip, which may be acceptable in many applications. Results
for the retrieved phase and recovered images are presented for some
one-dimensional objects and for different noise levels. Extensions
to objects of two dimensions are discussed. Requirements for signal-to-noise
ratio are derived for intensity interferometry with use of the proposed
processing.},

Now that astronomical telescopes are moving toward diffraction-limited
performance through the use of adaptive optics (AO), we address the
problem of coupling light into a few-mode fibre (FMF). We find that
fibres with as few as 5 guided modes share important characterisitcs
with multimode fibres, in particular high coupling efficiency. We

that outshines the broadband visible light of the Sun by 4 orders
of magnitude. This is a conservative lower bound for the technical
capability of a communicating civilization; optical interstellar
communication is thus technically plausible. We have built a pair
of systems to detect nanosecond pulsed optical signals from a target
list that includes some 13,000 Sun-like stars, and we have made some
16,000 observations totaling nearly 2400 hr during five years of
operation. A beam splitter-fed pair of hybrid avalanche photodetectors
at the 1.5 m Wyeth Telescope at the Harvard/Smithsonian Oak Ridge
Observatory (Agassiz Station) triggers on a coincident pulse pair,
initiating measurement of pulse width and intensity at subnanosecond
resolution. An identical system at the 0.9 m Cassegrain at Princeton's
Fitz-Randolph Observatory performs synchronized observations with
0.1 microsecond event timing, permitting unambiguous identification
of even a solitary pulse. Among the 11,600 artifact-free observations
at Harvard, the distribution of 274 observed events shows no pattern
of repetition, and is consistent with a model with uniform event
rate, independent of target. With one possible exception (HIP 107395),
no valid event has been seen simultaneously at the two observatories.

prevalence of civilizations transmitting intense optical pulses.},

abstract = {This paper considers the Hanbury Brown-Twiss effect and its application
to astrometry in the service of extra-solar planet detection, particularly
terrestrial planets at a range of 15 pc or less. The system considered
comprises several modest-sized telescopes (light collectors) each
equipped with photodetection apparatus and the means to record the
photodetector signal time-history. At some convenient location, the
cross-correlations of the individual light collector photodetection
histories is computed to yield, in turn, a collection of values for
the magnitudes of the mutual coherence of the target scene at various
measurement baselines. With this type of observation system, we show
that if there are known guide stars within the picture frame, the
computed coherence magnitudes may be used to infer the apparent motion
of the target star. Provided sufficiently large measurement baselines,
the resolution of the target star motion can be very fine. We first
compute the signal-to-noise (SNR) ratio of a single coherence magnitude
measurement and then, using simple models of the telescope array
and the target star gravitational perturbation due to a terrestrial
planet, we compute the SNR for determination of the planet orbit
parameters, up to the determinacy afforded by astrometric measurements.
We have provided expressions for the region in the (planetary mass-orbital
semi-major axis) plane for which SNR is above a desired value. With
these results, we can determine the sensitivity and range of the
overall instrument for astrometry in planet detection. Moreover,
one can assess the relative advantages of this technique in comparison
with amplitude interferometry.},

abstract = {We present the results of a photometric BVI survey of 0.9 deg2 around
the Wolf–Rayet binary Gamma2 Vel and its early-type common proper
motion companion Gamma1 Vel (together referred to as the gamma Vel
system). Several hundred pre-main-sequence (PMS) stars are identified
and the youth of a subset of these is spectroscopically confirmed
by the presence of lithium in their atmospheres, Halpha emission
and high levels of X-ray activity. We show that the PMS stars are
kinematically coherent and spatially concentrated around gamma Vel.
The PMS stars have similar proper motions to gamma Vel, to main-sequence
(MS) stars around gamma Vel and to early-type stars of the wider
Vela OB2 association of which gamma2 Vel is the brightest member.
The ratio of MS stars to low-mass (0.1–0.6 M) PMS stars is consistent
with a Kroupa mass function. MS fitting to stars around gamma Vel
gives an association distance modulus of 7.76 ± 0.07 mag, which is
consistent with a similarly determined distance for Vela OB2 and
also with interferometric distances to gamma2 Vel. High-mass stellar
models indicate an age of 3–4 Myr for gamma2 Vel, but the low-mass
PMS stars have ages of approx 10 Myr according to low-mass evolutionary
models and 5-10 Myr by empirically placing them in an age sequence
with other clusters based on colour-magnitude diagrams and lithium
depletion. We conclude that the low-mass PMS stars form a genuine
association with gamma Vel, and this is a subcluster within the larger
Vela OB2 association. We speculate that gamma2 Vel formed after the
bulk of the low-mass stars, expelling gas, terminating star formation
and unbinding the association. The velocity dispersion of the PMS
stars is too low for this star-forming event to have produced all
the stars in the extended Vela OB2 association. Instead, star formation
must have been initiated at several sites within a molecular cloud
either sequentially or simultaneously after some triggering event.},

make measurements with a spectral resolution of R > 107 and an angular

abstract = {After the discovery of space masers based on OH radicals (Weaver et
al.cite{Wea65}) and H2O (Cheung et al. cite{Che69}) such
microwavelasers have been found to work in more than 100 molecular
species(Elitzur cite{Eli92}; Townes cite{Tow97}), as well as in highlyexcited
H atoms (Strelnitski et al. cite{Str96}). In the IR region (10mum),
the effect of stimulated emission of radiation in the CO2molecule
has been discovered in the Martian and Venus' atmospheres (Betzet
al. cite{Bet76}; Mumma et al. cite{Mum81}). We report here on thediscovery
of laser action in the range 0.9-2 microns in several spectrallines
of Fe II, which are associated with transitions from``pseudo-metastable''
states populated by spontaneous transitions from Lyalpha pumped Fe
II levels. The intense Lyalpha radiation is formedin the HII region
of gas condensations close to the star eta Car. Thelaser transitions
form together with spontaneous transitions closedradiative cycles,
one of which includes the extremely bright 2507/09Angstroms lines.
Closed radiative cycles, together with an accidentalmixing of energy
levels, may provide an explanation of the abnormalintensities of
these UV non-lasing lines. Using the complicated energylevel diagram
of Fe II we present those peculiar features, which areessential for
the inverted population and laser effect: the pumping, thelevel mixing,
and the 'bottle neck' for spontaneous decay. The laseraction is a
new indicator of non-equilibrium and spatiallynon-homogeneous physical
conditions as well as a high brightnesstemperature of Lyalpha in
ejecta from eruptive stars. Such conditionsare very difficult to
probe by existing methods, and we propose somefuture experiments.
The fact, that the lasing near-IR lines appear inthe spectrum with
about the same intensity as non-lasing lines isdiscussed and compared
with the situation in masers.},

we propose novel temporal and spectral engineering techniques to
eliminate these detrimental decoherence effects. The temporal engineering
of the two-photon wavefunction results in a universal Bell-state
synthesizer that is independent of the choice of pump source, crystal
parameters, wavelengths of the interacting photons and the bandwidth
of the spectral filter. In the spectral engineering technique, the
distinguishing spectral features of the two-photon state are eliminated
through modifications to the two-photon source. In addition, spectral
engineering also provides a means for the generation of polarization-entangled
states with novel spectral characteristics: the frequency-correlated
state and the frequency-uncorrelated state.},

abstract = {The use of IR heterodyne spectroscopy for the study of planetary atmospheres
is discussed. Infrared heterodyne spectroscopy provides a convenient
and sensitive method for measuring the true intensity profiles of
atmospheric spectral lines. Application of radiative transfer theory
to measured line shapes can then permit the study of molecular abundances,
temperatures, total pressures, excitation conditions, and dynamics
of the regions of line formation. The theory of formation of atmospheric
spectral lines and the retrieval of the information contained in
these molecular lines are illustrated. Notable successes of such
retrievals from IR heterodyne measurements on Venus, Mars, Jupiter,
and earth are given. A discussion of new developments in IR heterodyne
technology is also presented.},

abstract = {We have estimated the contribution of atmospheric turbulence effects
to the satellite laser ranging precision. This work was motivated
by the observed discrepancy between the precision of laser ranging
to short baseline ground targets and space born targets. The contribution
of the atmosphere is expected to be the limiting factor to the satellite
laser ranging precision on millimeter level. Two different atmospheric
optical models were investigated. The geometry approach showed that
at some situations the turbulence-induced random ranging error could
reach the millimeter level, as observed in laser ranging experiment.
This effect significantly decreases with the station’s altitude above
sea level and satellite altitude above horizon. The results depend
on the value of the atmospheric outer scale parameter; its value
is only approximate due to hardly predictable nature of the turbulence
strength height profile. A novel experiment with high repetition
rate satellite laser ranging is introduced, which should prove the
turbulence contribution to the satellite laser ranging precision.},

Most existing algorithms to correct for event count errors due to
dead time implicitly rely on Poisson counting statistics of the underlying
phenomena. However, when the events to be measured are clustered
in time, the Poisson statistics assumption results in underestimating
both the true event count and any statistics associated with count
variability; the ‘busiest’ part of the signal is partially missed.
Using the formalism associated with the pair-correlation function,
we develop first-order correction expressions for the general case
of arbitrary counting statistics. The results are verified through
simulation of a realistic clustering scenario.},

abstract = {We present the most intensive, high-quality spectroscopic monitoring
of optical Wolf-Rayet emission lines ever obtained. The Wolf-Rayet
star HD 192103 (=WR135; subtype WC8) was observed in the 5650-5840A
regime alternately from both the William Herschel Telescope and the
Canada-France-Hawaii Telescope. The final data consist of a series
of 197 spectra spread over 64 hr, each with a resolving power lambda/dlambda~=20,000
and a signal-to-noise ratio in the continuum ~=450 per 3 pixel resolution
element. We clearly and unambiguously identify stochastic, structured
patterns of intrinsic variability at the 1%-2% level of the line
flux in the broad C III 5696A emission line. The lambda5801/12 doublet
emission is also found to be variable at the 0.2%-0.5% level of the
line flux. We find a correlation between the variability patterns
observed in C III and C IV, which suggests a significant overlap
in the emission volumes of these transitions, although C IV is known
to arise somewhat closer to the star. We attempt to reproduce the
observed line profile variation patterns using a simple phenomenological
model, which assumes the wind to be fully clumped. With a minimal
set of assumptions, we are able to reproduce both the shape and the
variability in the C III 5696A emission profile. We show that the
variability pattern provides constraints on the radial extent of
WR 135's wind where C III is produced, as well as on the local wind
acceleration rate. However, our simple clump model does not reproduce
the lower variability in the C IV doublet unless we assume the C
IV emission to occur in a much larger volume than C III, implying
that significant C IV emission occurs farther out in the wind than
C III. We suggest that while some C IV emission might occur farther
out, possibly because of reionization from shocks, a more likely
explanation is that wind clumping significantly increases with distance
from the star, leading to larger variability levels in C III, formed
farther out than most of C IV. Alternatively, optical depth effects
and/or local ionization gradients within clumps could conspire to
attenuate clumping effects in the C IV emission line while enhancing
them in the C III line.},

of interstellar star-forming molecular clouds. Progress in observational
astronomy, particularly with ground-based huge telescopes and the
space-based Hubble Space Telescope, has led to recent discoveries
of space lasers in the optical range. These operate in gas condensations
in the vicinity of the mysterious star Eta Carinae (one of the most
luminous and massive stars of our Galaxy). Both maser and laser effects,
first demonstrated under laboratory conditions, have now been discovered
to occur under natural conditions in space too. This book describes
consistently the elements of laser science, astrophysical plasmas,
modern astronomical observation techniques, and the fundamentals
and properties of astrophysical lasers.},

second-order degree of coherence is reduced as the rotating speed
decreases. This result can be well explained by the model of mixed

abstract = {We present a method of directly testing whether time continues to
have its usual meaning on scales of < t p (G/c5 )1/2 < 5.4#1044
s, the Planck time. According to quantum gravity, the time t of an
event cannot P be determined more accurately than a standard deviation
of the form a, where and a are positive j /t p a (t /t) a t 0 P 0
constants near 1; likewise, distances are subject to an ultimate
uncertainty cjt , where c is the speed of light. As a consequence,
the period and wavelength of light cannot be specified precisely;
rather, they are independently subject to the same intrinsic limitations
in our knowledge of time and space, so that even the most monochromatic
plane wave must in reality be a superposition of waves with varying
q and k, each having a different phase velocity q/k. For the entire
accessible range of the electromagnetic spectrum this effect is extremely
small, but it can cumulatively lead to a complete loss of phase information
if the emitted radiation propagated a sufficiently large distance.
Since, at optical frequencies, the phase coherence of light from
a distant point source is a necessary condition for the presence
of diffraction patterns when the source is viewed through a telescope,
such observations offer by far the most sensitive and uncontroversial
test. We show that the Hubble Space Telescope detection of Airy rings
from the active galaxy PKS 1413135, located at a distance of 1.2
Gpc, excludes all first-order (a p 1) quantum gravity fluctuations
with an amplitude a 1 0.003. The same result may be used to deduce
that 0 the speed of light in vacuo is exact to a few parts in 1032.},

can be temporarily blinded by relatively bright light, of intensity
less than a nanowatt. I describe a bright-light regime suitable for
attacking a quantum key distribution system containing such detectors.
In this regime, all single photon detectors in the receiver Bob are
uniformly blinded by continuous illumination coming from the eavesdropper
Eve. When Eve needs a certain detector in Bob to produce a click,
she modifies polarization (or other parameter used to encode quantum
states) of the light she sends to Bob such that the target detector
stops receiving light while the other detector(s) continue to be
illuminated. The target detector regains single photon sensitivity
and, when Eve modifies the polarization again, produces a single
click. Thus, Eve has full control of Bob and can do a successful
intercept-resend attack. To check the feasibility of the attack,
3 different models of passively-quenched detectors have been tested.
In the experiment, I have simulated the intensity diagrams the detectors
would receive in a real quantum key distribution system under attack.
Control parameters and side effects are considered. It appears that
the attack could be practically possible.},

attack in the case of a partial efficiency mismatch on the Scarani-Acin-Ribordy-Gisin

a function of detector efficiencies. Additionally, it is shown how

1950s and 60s by Hanbury Brown and collaborators, achieving milli-arcsec
resolutions in visible light without optical-quality mirrors. They
exploited a then-novel physical effect, nowadays known as HBT correlation
after the experiments of Hanbury Brown and Twiss, and considered
fundamental in quantum optics. Now a new generation of intensity
inter- ferometers is being designed, raising the possibility of measuring
intensity correlations with three or more detectors. Quantum-optics
predicts two interesting features in many-detector HBT: (i) the signal
contains spatial information about the source (such as the bispectrum
or closure phase) not present in standard HBT, and (ii) correlation
increases combinatorially with the number of detectors. The signal
to noise ratio (SNR) depends crucially on the number of photons —
in practice always << 1 — detected per coherence time. A simple SNR
formula is derived for thermal sources, indicating that three-detector
HBT is feasible for bright stars. The many-detector enhancement of
HBT would be much more difficult to measure, but seems plausible
for bright masers.},

volume = {358},
abstract = {In this paper we derive stellar parameters for the Wolf-Rayet star
in the gamma Velorum binary system (WR11), from a detailed non-LTE
model of its optical and infrared spectra. Compared to the study
of Schaerer et al., the parameters of the WC8 star are revised to
a hotter effective temperature (T_eff ~ 57 kK), a higher luminosity
(log (L/Lsun) = 5.00), and a lower mass-loss rate (log(dot {M} /
Msun/yr) = -5.0, using a 10% clumping filling factor). These changes
lead to a significant decrease in wind efficiency number, from 144
to 7, so that the driving mechanism of the wind of this WR star may
be simply radiation pressure on lines. The derived spectroscopic
luminosity is found to be 40% lower than that derived by De Marco
& Schmutz through the mass-luminosity relationship for WR stars (log
(L/Lsun) = 5.2). The paper furthermore presents a comparison of the
independently-developed modelling programs, cmfgen and isa-wind.
Overall, there seems to be very reasonable agreement between the
derived parameters for WR11, except for the carbon content, which
is 2 times higher for cmfgen (C/He=0.15 vs. 0.06, by number). The
comparison also confirms a disparity in the predicted flux at $lambda
mbda$<400 Ä, found by Crowther et al., which will have effects on
several nebular line strengths. The paper also presents the first
independent check of the photon loss mechanism proposed by Schmutz.
We conclude that, not only is it important to include very many lines
to realistically model line blanketing, but in particular those ones
that critically interact with strong resonance lines (e.g. He ii\
lambda 303.78). The inclusion of these latter lines may significantly
alter the wind ionization structure. Based on observations collected

abstract = {Direct detection of photons from exoplanets in the habitable zone
around nearby stars is challenging because of the much higher photon
flux and close angular proximity of the star. At mid-infrared wavelengths,
around 10 micrometre, the flux contrast ratio between a sun-like
star and an earth-size planet is several million to one, favorable
compared to the visible range, while the angular separation of the
bodies is less than 1 microradian. The wavelength range between 7
and 20 micrometre is worthy of study because it can yield information
on the planetary atmospheric composition, particularly as it contains
absorption lines for CO2, ozone and water, which together can be
considered a biomarker under some conditions. To achieve observations
of the spectrum, strong and stable suppression of the excess starlight
is required along with suppression of the local and exo-Zodiacal
light, which also have much higher fluxes than the exoplanet signal.
Here we show in the laboratory with nulling interferometry, the suppression
of artificial starlight by almost eight orders of magnitude, which
is sufficient to detect a planet some three million times fainter
than the star. The results show that a combination of starlight suppression
techniques enables the detection of medium-sized planets in the habitable
zone around nearby stars. Large space telescopes planned for future
exoplanet studies will employ these techniques and one additional
method, which brings earth-size planets within reach to obtain compelling
data on the atmospheres of nearby exoplanets.},

etc., in spectra obtained with the Hubble Space Telescope/Space Telescope
Imaging Spectrograph instrument during 1998-2004. Our principal results,
some of them unexpected, are as follows. (1) The high-excitation
fluxes varied systematically and nontrivially throughout eta Car’s
5.5 year spectroscopic cycle. Instead of rising to a plateau after
the 1998 “event,” they changed continuously with a maximum in mid-cycle.
(2) At one significant location a brief, strong secondary maximum
occurred just before the 2003.5 spectroscopic event. (3) These emission
lines are strongly concentrated at the “Weigelt knots” several hundred
AU northwest of the star. With less certainty, [Ne iii] appears to
be somewhat more concentrated than [Fe iii]. (4) A faster, blueshifted
component of each feature appears concentrated near the star and
elongated perpendicular to the system’s bipolar axis. This structure
may be related to the equatorial outflow and/or to dense material
known to exist along our line of sight to the star. (5) Using the
photoionization program Cloudy, we estimated the range of parameters
for the hot secondary star that would give satisfactory high-excitation
line ratios in the ejecta. Teff approx 39,000 K and L - 4 x 105 L,
for example, would be satisfactory. The allowed region in parameter
space is wider (and mostly less luminous) than some previous authors
suggested.},

The radiative transfer equation is written in microscopic form, and
from some simplifications on the ratio of occupation numbers for
upper and lower level, a laser action is suggested. I like to write
the equation of radiative transfer for line absorption in a plane-parallel
atmosphere in the following exact form: mu dI/dr = -(n1-n2 g1/g2)I
alpha + (2hv^3/c^2)(n2 g1/g2)alpha (1) where I is the specific intensity
and alpha is the atomic absorption coefficient at frequency, v. The
quantities n1 and n2 are the atomic populations of the lower and
upper levels, whose respective statistical weights are g1 and g2.
In thermodynamic equilibrium, a single parameter T, the absolute
temperature, governs the Boltzmann and Planck formulas, so that n2/n1
= (g2/g1) exp(-hv/kT) (2) I = (2hv^3/c^2) / [exp(hv/kT) - 1] When
these equations are substituted into (1) the right-hand side vanishes,
as it must for thermodynamic equilibrium, since the intensity is
isotropic and independent of position. In equation (1), the second
term in the parenthesis represents the stimulated emission or, as
it should more properly be called, the negative absorption. Too many
astrophysicist either combine it with the random emission, the second
term on the right-hand side, or neglect it altogether. The true source
function takes the form of the second term on the right-hand side
of (1), which in no sense resembles a Planck function except when
hv is much greater than kT. The quantities n1 and n2 are to be calculated
from the equations of statistical equilibrium, which involve collisional
excitation and de-excitation as well as radiative processes. Many
years ago, in problems related to gaseous nebulae, I introduced a
dimensionless parameter, b, to indicate the degree of departure of
a gas from thermodynamic equilibrium at temperature T of the electron
gas. This parameter equalled unity for thermodynamic equilibrium.
Thus I could write n2/n1 = [ b2 g2 /(b1 g1) ] exp(-hv/kT) (3) with
which expression (1) becomes dI/dh cos theta = - n1 alpha [(1 - (b2/b1)exp(-hv/kT))
I + 2hv^3/c^2(b2/b1)exp(-hv/kT)] (4) As long as hv/kT was much greater
than 1, we can usually neglect the term representing the stimulated
emission. And, as long as b2/b1 does not depart too far from unity,
the second term on the right hand side is approximately equal to
the source function. Many studies have shown that the b's exhibit
the following behavior for nebulae and, presumably, also for stars
with highly distended atmospheres. First of all, b's for ground or
metastable levels tend to be high. Second, the first excited levels
directly above the ground level tend to have b's much less than unity.
Third, the b's for still higher levels slowly tend to unity at the
series limit. For all lines except those from the ground or metastable
levels, then, b2/b1 will exceed unity. And when the temperature is
high enough, the stimulated emission may exceed the ordinary absorption
so that dI/dh cos theta = n1 alpha(b2/b1)exp(-hv/kT)[ 2hv^3/c^2 +
I ] (5) Since this term is essentially positive, the emission line
increases in intensity with depth. (exponentially) The process is
self-limiting, however, since an increase in the intensity of the
incident radiation causes the medium to approach local thermodynamic
equilibrium. However, as long as the energy is 'diluted', some sort
of laser action will occur. Laser History Laser Stars},

year = {2015},
month = {July},
pages = {392-393},
volume = {523},
abstract = {You could say that the silence has been deafening. Since its beginnings
more than half a century ago, the dedicated search for extraterrestrial
intelligence (SETI) has failed to detect the presence of alien civilizations.
But at London’s Royal Society today (20 July), Russian billionaire
Yuri Milner announced a shot in the arm for SETI: a US\$100-million
decadal project to provide the most comprehensive hunt for alien
communications so far. The initiative, called Breakthrough Listen,
will see radio telescopes at Green Bank in West Virginia, the Parkes
Observatory in Australia, and the Lick Observatory's optical telescope
in San Jose, California, scanning around one million stars in the
Milky Way and a hundred nearby galaxies. Milner is also releasing
an open letter backing the idea of an intensified search; it has
been co-signed by numerous scientists, including physicist Stephen
Hawking. “In an infinite Universe, there must be other life,” Hawking
told luminaries at today's launch event. “There is no bigger question.
It is time to commit to finding the answer,” he said. “We would typically
get 24–36 hours on a telescope per year, but now we’ll have thousands
of hours per year on the best instruments,” says one of the project
leaders, Andrew Siemion, a SETI scientist at the University of California,
Berkeley. “It’s difficult to overstate how big this is. It’s a revolution.”
Related stories Climate scientists join search for alien Earths Hubble
successor will struggle to hunt alien life Science prizes: The new
Nobels More related stories SETI projects traditionally search for
radio or optical signals that seem to be from an artificial source,
for instance because they are focused in frequency and repeat in
a regular manner. But funding has been patchy: in the early 1990s,
NASA sponsored some searches, but dropped that support in 1993. “In
recent years, the total worldwide support for SETI was about half
a million dollars, mostly in the United States, and all from private
gifts,” says Frank Drake, one of the pioneers of modern SETI, who
is also on the Breakthrough Listen team. “Now we’re getting $100
million, so that’s real progress.” Milner, who is bankrolling the
project, made his fortune through investments in Facebook and other
Internet businesses, and in 2012 established lucrative ‘Breakthrough’
prizes to reward excellence in the life sciences, fundamental physics,
and mathematics. A particle-physics graduate, he jokes that his interest
in SETI began in 1961, the year of his birth; he was named after
Russian cosmonaut Yuri Gagarin, instilling a life-long fascination
with space and the possibility of alien life. Paul Davies, a cosmologist
and long-term supporter of SETI at Arizona State University in Tempe,
who is not involved with Breakthrough Listen, says that he is “thrilled”
by Milner's initiative: “It's fantastic that there still exist individuals
who are not just rich but who have a cosmic vision that the whole
of humanity can get behind,” he says. Data torrent The small SETI
community will be inundated with a torrent of data — potentially
as much in a day as earlier SETI projects collected in a year, Milner
estimates. The data will be publicly available, to allow enthusiasts
to join the search; Breakthrough Listen will also partner with the
established SETI@home project that connects people’s home computers
and uses them to crunch data. “The results belong to everyone equally,”
says Milner, adding that transparency is particularly important in
a project searching for aliens because “there are so many conspiracy
theorists”. He also plans a Breakthrough Message competition — offering
a $1-million pool of prize money — to construct a digital message
to transmit to potential extraterrestrials (though there is no commitment
to sending out the message). Drake argues that Breakthrough Listen
will have a positive impact on the wider astronomy community. The
investment has saved the relatively old Green Bank and Parkes telescopes
from the threat of closure, he says, as governments divert funds
to larger-scale, higher-resolution projects such as the Square Kilometre
Array (SKA). And the sky survey might discover more pulsars, and
help to home in on the origin of mysterious “fast radio bursts” —
pulses lasting only a few milliseconds. Karen O'Neil, director of
the Green Bank site, says the "fantastic collaboration", which will
see the project underwriting 20% of the telescope's costs in return
for 20% of its operating time, has been a lifeline. "It goes a long
way to helping us, although it doesn't completely solve the problem,"
she says. "If we weren't concerned about overall funding it would
be a difficult question for us whether this is the right path forward
in order to allow people guaranteed time on the telescope. But we
do need this and there's the real possibility that through this funding
we'll be able to keep the telescope open at least partway for astronomers
to keep using it." O'Neil is working with the US National Science
Foundation to find other sources of funding to keep the telescope
open. Alex Cherney, terrastro.com/SPL Star trails over Parkes Observatory
in New South Wales, Australia; another telescope that will be used
in the Breakthrough Listen project. Breakthrough Listen has not finalized
its search strategy, but one of the project’s first tasks will be
to fully scan stars for signals in the frequency band between about
1 gigahertz (GHz) and 10 GHz (including the region known as the water
hole, because it includes frequencies at which H and OH emit radio
waves). The band has been identified in the past as a good channel
for deliberate alien communication because signals can travel through
interstellar space and Earth’s atmosphere without much interference.
“Previously we’ve only been able to hunt and peck at it, now we’ll
search that entire spectrum comprehensively,” says Siemion. Davies
suggests that the investment is a good time to rethink the conventional
SETI strategy of moving a telescope from star to star, watching each
for only a short time. That might not work, he says, because it would
require a distant civilization to be sending a constant electromagnetic
signal specifically to Earth, when aliens — if they exist — are more
likely to be sending a ‘lighthouse beacon’ that sweeps around the
sky. "I think SETI needs to revise its strategy and point its telescope
towards the centre of the Galaxy for many years to maximize the chance
of picking up such a transient signal," he says. “It’s quite likely
that we won’t find anything,” Milner concedes, adding that a negative
result would allow astronomers to put some limits on what is out
there. “But in 10 years’ time, there will be even more advances and
we can work out the best strategy for the next 10 years of the project,
and then maybe the next 10 after that,” he says.},

On sufticiently small time scales the system evolves by a random sequence of unitary phase changes generated by the Hamiltonian.

The rate of coherence loss becomes very large as the energy scale of the system is increased. The expansion parameter determines an uncertainty in the time step on very short times scales. A number of testable consequences are derived including anomalous dispersion of a free particle, decay of oscillatory systems, destruction of interference-fringe visibility, and a phase shift of interference fringes.},

the photon-limited wavelength calibration precision achievable with
existing echelle spectrographs should be 1 cm s-1 when integrated
over a 4000 Å range. Moreover, comb spectra may be used to accurately
characterize distortions of the wavelength scale introduced by the
spectrograph and detector system. The simulations show that frequency
combs with pulse repetition rates of 5-30 GHz are required, given
the typical resolving power of existing and possible future echelle
spectrographs. Achieving such high repetition rates, together with
the desire to produce all comb modes with uniform intensity over
the entire optical range, represents the only significant challenges
in the design of a practical system. Frequency comb systems may remove
wavelength calibration uncertainties from all practical spectroscopic

presented analyses with the Hubble Space Telescope/Space Telescope
Imaging Spectrograph (HST/STIS) in the UV (1240-3159 angstros) to
10430 angstroms. The spectrum in the mid- and near-UV is characterized
by the ejecta absorption. At longer wavelengths, stellar wind features
from the central source and narrow-emission lines from the Weigelt
condensations dominate the spectrum. However, narrow absorption lines
from the circumstellar shells are present. This paper provides a
description of the spectrum between 3060 and 10430 angstroms, including
line identifications of the ejecta absorption spectrum, the emission
spectrum from the Weigelt condensations and the P Cygni stellar wind
features. The high spectral resolving power of VLT/UVES enables equivalent
width measurements of atomic and molecular absorption lines for elements
with no transitions at the shorter wavelengths. However, the ground-based
seeing and contributions of nebular-scattered radiation prevent direct
comparison of measured equivalent widths in the VLT/UVES and HST/STIS
spectra. Fortunately, HST/STIS and VLT/UVES have a small overlap
in wavelength coverage which allows us to compare and adjust for
the difference in scattered radiation entering the instruments' apertures.
This paper provides a complete online VLT/UVES spectrum with line

system contains the closest example of a Wolf-Rayet star and the
promise of full characterisation of the basic properties of this
exotic high-mass system has subjected it to intense study as an archetype
for its class. In combination with the latest radial-velocity results,
our orbital solution produces a distance of 336^{+8}_{-7} pc, significantly
more distant than the Hipparcos estimation (Schaerer et al. 1997/
van der Hucht 1997). The ability to fully specify the orbital parameters
has enabled us to significantly reduce uncertainties and our result
is consistent with the VLTI observational point (Millour et al. 2006),
but not with their derived distance. Our new distance, which is an
order of magnitude more precise than prior work, demands critical
reassessment of all distance-dependent fundamental parameters of
this important system. In particular, membership of the Vela OB2
association has been reestablished, and the age and distance are
also in good accord with the population of young stars reported by
Pozzo et al. (2000). We determine the O-star primary component parameters
to be M_V(O) = -5.63 \pm 0.10 mag, R(O) = 17 \pm 2 R_{\sun} and {\cal

title = {Towards Optical Intensity Interferometry For High Angular Resolution Stellar Astrophysics},
year = {2012},
abstract = {Most neighboring stars are still detected as point sources and are
beyond the angular resolution reach of current observatories. Methods
to improve our understanding of stars at high angular resolution
are investigated. Air Cherenkov telescopes (ACTs), primarily used
for Gamma-ray astronomy, enable us to increase our understanding
of the circumstellar environment of a particular system. When used
as optical intensity interferometers, future ACT arrays will allow
us to detect stars as extended objects and image their surfaces at
high angular resolution. ACTs are used in gamma-ray astronomy to
investigate violent phenomena in the universe. However, this technique
can also be used for stellar astrophysics on some isolated sources.
Such is the case with the X-ray binary LS I +61303 which was detected
in the TeV range. A gamma-ray attenuation model is developed and
applied to this system. This models allows us to place constraints
on fundamental properties of the system. However, a much better understanding
of this system, and more so of nearby bright stellar systems, could
be obtained with high angular resolution techniques. Optical stellar
intensity interferometry (SII) with ACT arrays, composed of nearly
100 telescopes, will provide means to measure fundamental stellar
parameters and also open the possibility of model-independent imaging.
A data analysis algorithm is developed and permits the reconstruction
of high angular resolution images from simulated SII data. The capabilities
and limitations of future ACT arrays used for high angular resolution
imaging are investigated via Monte-Carlo simulations. Simple stellar
objects as well as stellar surfaces with localized hot or cool regions
can be accurately imaged. Finally, experimental efforts to measure
intensity correlations are expounded. The functionality of analog
and digital correlators is demonstrated. Intensity correlations have
been measured for a simulated star emitting pseudo-thermal light,
resulting in angular diameter measurements. The StarBase observatory,
consisting of a pair of 3m telescopes separated by 23m, is described.},

abstract = {Stellar amplitude interferometry is limited by the need to have optical
distances known to a fraction of the wavelength. We suggest reviving
intensity interferometry, which requires far less accurate hardware
(~1cm mechanical precision) at the cost of more limited sensitivity.
We present an algorithm that uses the very high redundancy of a uniform
linear array to increase the sensitivity of the instrument by more
than a hundredfold. An array of a hundred ~100m diameter elements
can achieve a limiting magnitude of m b=14.4. Off-line processing
of the data will enable such a ground-based facility to transform
a two-dimensional field of point-like sources to a three-dimensional
distribution of micro-arcsec resolved systems, each imaged in several
optical bands. Each system will also have its high resolution residual
timing, high quality (inside each band) spectra and light curve,
emergent flux, effective temperature, polarization effects and perhaps
some thermodynamic properties, all directly measured in a single
observation run of such a dedicated facility. Coronagraphy, selectively
suppressing large scale structures of the sources, can also be achieved
by specific aperture shapes. We conclude that after three decades
of abandonment optical intensity interferometry deserves another
review, also as a ground-based alternative to the science goals of
space interferometers.},

central to understanding the hydrologic cycle and potential for extant
life on Mars. Recurring slope lineae, narrow streaks of low reflectance
compared to the surrounding terrain, appear and grow incrementally
in the downslope direction during warm seasons when temperatures
reach about 250-300 K, a pattern consistent with the transient flow
of a volatile species1, 2, 3. Brine flows (or seeps) have been proposed
to explain the formation of recurring slope lineae1, 2, 3, yet no
direct evidence for either liquid water or hydrated salts has been
found4. Here we analyse spectral data from the Compact Reconnaissance
Imaging Spectrometer for Mars instrument onboard the Mars Reconnaissance
Orbiter from four different locations where recurring slope lineae
are present. We find evidence for hydrated salts at all four locations
in the seasons when recurring slope lineae are most extensive, which
suggests that the source of hydration is recurring slope lineae activity.
The hydrated salts most consistent with the spectral absorption features
we detect are magnesium perchlorate, magnesium chlorate and sodium
perchlorate. Our findings strongly support the hypothesis that recurring
slope lineae form as a result of contemporary water activity on Mars.},

visibility of the interference pattern, is governed by the degree
of distinguishability among different pairs of photons. Based on
this discovery, we generalize the concept of multi-photon temporal

effects. Finally, we make an attempt to interpret the coherence theory

Chandra to set the constraint & 0:58, which rules out the random

detections of quasars at GeV energies with Fermi, and at TeV energies

Hawking radiation [1], are typically assumed to be only relevant
at extreme physical conditions: at high energies and in strong gravitational
fields. Here we consider low-energy quantum mechanics in the presence
of weak gravitational time dilation and show that the latter leads
to universal decoherence of quantum superpositions. Time dilation
induces a universal coupling between internal degrees-of-freedom
and the centre-of-mass of a composite particle and we show that the
resulting entanglement causes the particle’s position to decohere.
We derive the decoherence timescale and show that the weak time dilation
on Earth is already sufficient to decohere micro-scale objects. No
coupling to an external environment is necessary, thus even completely
isolated composite systems will decohere on curved space-time. In
contrast to gravitational collapse models [2, 3], no modification
of quantum theory is assumed. General relativity therefore can account
for the emergence of classicality and the effect can in principle
be tested in future matter wave experiments with large molecules

stringent limits on the effects of Planck-scale phenomenology.},

abstract = {Many imaging applications require increasingly bright illumination
sources, motivating the replacement of conventional thermal light
sources with bright light-emitting diodes, superluminescent diodes
and lasers. Despite their brightness, lasers and superluminescent
diodes are poorly suited for full-field imaging applications because
their high spatial coherence leads to coherent artefacts such as
speckle that corrupt image formation. We recently demonstrated that
random lasers can be engineered to provide low spatial coherence.
Here, we exploit the low spatial coherence of specifically designed
random lasers to demonstrate speckle-free full-field imaging in the
setting of intense optical scattering. We quantitatively show that
images generated with random laser illumination exhibit superior
quality than images generated with spatially coherent illumination.
By providing intense laser illumination without the drawback of coherent
artefacts, random lasers are well suited for a host of full-field
imaging applications from full-field microscopy to digital light
projector systems.},

year = {2015},

volume = {150},
abstract = {We report on high-resolution spectroscopy of the 2009.0 spectroscopic
event of Eta Carinae collected via SMARTS observations using the
CTIO 1.5 m telescope and echelle spectrograph. Our observations were
made almost every night over a two-month interval around the photometric
minimum of Eta Car associated with the periastron passage of a hot
companion. The photoionizing flux of the companion and heating related
to colliding winds causes large changes in the wind properties of
the massive primary star. Here we present an analysis of temporal
variations in a sample of spectral lines that are clearly formed
in the wind of the primary star. These lines are affected by a changing
illumination of the flux of the secondary star during the periastron
passage. We document the sudden onset of blueshifted absorption that
occurred in most of the lines near or slightly after periastron,
and we argue that these absorption components are seen when we view
the relatively undisturbed wind of the foreground primary star. We
present time series measurements of the net equivalent width of the
wind lines and of the radial velocities of the absorption trough
minima and the emission peak midpoints. Most lines decrease in emission
strength around periastron, and those high excitation lines formed
close to the primary exhibit a red-ward velocity excursion. We show
how these trends can be explained using an illuminated hemisphere
model that is based on the idea that the emission originates primarily
from the side of the primary facing the hot companion.},

a more thorough formulation of the quantized field, starting from
a Lorentz invariant formulation, which is then explicitly broken
by the choice of a particular propagation direction. The effect of
the latter improvement in the quantization on the form of the final
equation is minimal.},

title = {Photoelectron Statistics: With Applications to Spectroscopy and Optical Communication},
year = {1978},
abstract = {With the recent great expansion in optics and laser applications,
several new areas of research have emerged, among which are: the
theory of coherence, photon statistics, speckle phenomenon, statistical
optics, atmospheric propa gation, optical communications, and light-beating
and photon-correlation spectroscopy. A factor common to these overlapping
subjects is their basic dependence on the treatment of light as a
randomly fluctuating excitation. Moreover, they all necessitate a
thorough understanding of the phenomenon of light detection and the
additional randomness it introduces. My objective in writing this
book is to provide a unified and general presentation of a basic
theoretical background central to these areas. This book has a threefold
purpose: to present a systematic treatment of the statistical properties
of optical fields, to develop methods for deter mining the statistics
of the photoelectron events that are generated when such fields are
intercepted by photodetectors, and to examine methods of estimating
unknown field parameters from measurements of the photoelectron events.
Emphasis is placed on the photoelectron measurements that yield in
formation pertinent to spectroscopy and optical communication. Although
some books that treat the theory of coherence and the statisti cal
properties of light are available, the vast body of information central
to problems of photoelectron statistics and its applications is scattered
in various professional journals and conference proceedings.},

It is shown that by using a resonant cavity of centimeter dimensions, having many resonant modes, maser oscillation at these wavelengths can be achieved by pumping with reasonable amounts of incoherent light. For wavelengths much shorter than those of the ultraviolet region, maser-type amplification appears to be quite impractical. Although use of a multimode cavity is suggested, a single mode may be selected by making only the end walls highly reflecting, and defining a suitably small angular aperture. Then extremely monochromatic and coherent light is produced. The design principles are illustrated by reference to a system using potassium vapor.},

local pumping of the atomic system, the spectrum of the laser emission

abstract = {We report the detection of the emission line He II lambda4686A in
eta Carinae. The equivalent width of this line is ~100 mA along most
of the 5.5 yr cycle and jumps to ~900 mA just before phase 1.0, followed
by a brief disappearance. The similarity between the intensity variations
of this line and those of the X-ray light curve is remarkable, suggesting
that they are physically connected. We show that the expected number
of ionizing photons in the ultraviolet and soft X-rays, expected
to be emitted in the shock front from the colliding winds, is of
the order of magnitude required to produce the He II emission via
photoionization. The emission is clearly blueshifted when the line
is strong. The radial velocity of the line is generally -100 km s-1,
decreases steadily just before the event, and reaches -400 km s-1
at phase 1.001. At this point, the velocity gradient suddenly changes
sign, at the same time that the emission intensity drops to nearly
zero. Possible scenarios for explaining this emission are briefly
discussed. The timing of the peak of He II intensity is likely to
be associated with the periastron and may be a reliable fiduciary
mark, important for constraining the orbital parameters.},

It however took more than seven decades for the ‘quantum granularity’ of light to be observed in the fluorescence of single atoms. Single atoms emit photons one at a time, this is typically demonstrated with a Hanbury-Brown-Twiss setup where light is split by a beam splitter and sent to two detectors resulting in anticorrelation of detected events. This setup, however, evokes the false impression that a beam splitter is necessary to prove indivisibility of photons. Here we show single-photon statistics from a quantum emitter with only one detector. The superconducting detector we fabricated has a dead time shorter than the coherence time of the emitter. No beam splitter is employed, yet anticorrelations are observed. Our work significantly simplifies a widely used photon-correlation technique.},

In particular, one can infer the orientation of the object’s transient trajectory. We identify the key parameters that impact this perturbation and show that its magnitude is equal to the magnitude of the intensity variation caused by the same object. In astronomy applications, this value may be very small, so a differential measurement may be necessary.

abstract = {Conventional ground-based astronomical observations suffer from image
distortion due to atmospheric turbulence. This can be minimized by
choosing suitable geographic locations or adaptive optical techniques,
and avoided altogether by using orbital platforms outside the atmosphere.
One of the promises of optical intensity interferometry is its independence
from atmospherically induced phase fluctuations. By performing narrowband
spectral filtering on sunlight and conducting temporal intensity
interferometry using actively quenched avalanche photon detectors
(APDs), the Solar g(2)(t) signature was directly measured. We observe
an averaged photon bunching signal of g(2)(t) = 1.693 +/- 0.003 from
the Sun, consistently throughout the day despite fluctuating weather
conditions, cloud cover and elevation angle. This demonstrates the
robustness of the intensity interferometry technique against atmospheric
turbulence and opto-mechanical instabilities, and the feasibility
to implement measurement schemes with both large baselines and long
integration times.},

to resolve the linewidth of narrow spectral emissions in starlight.
A combination of spectral
filtering with single-photon-level temporal correlation measurements

limit of wavelength-dispersing spectrographs by moving the linewidth
measurement into the

can determine a 20-MHz-wide linewidth of Doppler-broadened laser light

narrow emission lines in the wavelength region between 3640 and 7890
A using the Keck 10 meter telescope and spectroscopy with high resolution
(lamda/delta lambda = 60,000). Laser emission lines coming from non-natural
sources are distinguished from natural astrophysical sources by being
monochromatic and coming from an unresolved point in space. We search
for laser emission located 27 arcsec from the 2796 target stars.
The detectability of laser emission is limited by Poisson statistics
of the photons and scattered light, yielding a detection threshold
flux of 10-2 photons m-2s-1for typical Kepler stars and 1 photon
m-2s-1 for solar-type stars within 100 light-years. Diffraction-limited
lasers having a 10-meter aperture can be detected from 100 lightyears
away if their power exceeds 90 W, and from 1000 light-years away
(Kepler planets), if their power exceeds 1 kW (from lasers located
60-200 AU, and 2000-7000 AU from the nearby and Kepler stars, respectively).

year = {1995},
pages = {843},
volume = {300},
abstract = {We have detected four beta-lines out of six observed in the frequency
range from 100 to 400GHz toward the radio star MWC 349A. The detected
beta-lines have similar parameters as the pedestal features of the
short mm alpha-lines and probably have the same origin in the ionized
wind. We find that the flux ratios of beta- and alpha-line pedestals
of nearly the same frequency are much smaller than expected from
an optically thin plasma in LTE in all cases. We show with the help
of simplified NLTE models of the recombination line emission that
low beta/alpha-ratios are due to enhancement of the alpha-lines by
stimulated emission. This is a natural consequence of the high free-free
continuum opacity in the ionized wind of MWC 349A. The models also
predict that the beta/alpha-ratio is a sensitive probe of the electron
density. For the 33beta line emitting region the density thus derived
is compatible with previous estimates, n_e_~3.10^7^cm^-3^, based
on a model of the wind's continuum emission. The four newly detected
beta-lines provide, together with the high frequency alpha-line pedestals,
the most reliable value of the center velocity of the ionized outflow,
v_LSR_=8+/-3km/s. This value agrees well with the centroid velocity
of the disk, v_LSR_=8.2+/-.3km/s, as derived from the velocities
of the blue and red maser spikes, and thus represents the best estimate
of the stellar velocity. H32beta, at 366.6GHz the highest frequency
beta-line observed to date, displays on top of the pedestal two weak
narrow emission features whose velocities and widths are in qualitative
agreement with those of the alpha-line maser spikes. We tentatively
interpret these H32beta spikes as a weak disk maser whose estimated
optical depth, |tau|=<1, confirms earlier estimates of the alpha-line
maser gain (|tau|=~6).},

(SETI) should concentrate on attempts to receive signals in the microwave
region, the argument being given that communication can occur there
at minimum broadcasted power. Such a conclusion is shown to result
only under a restricted set of assumptions. If generalized types
of detection are considered—in particular, photon detection rather
than linear detection alone—and if advantage is taken of the directivity
of telescopes at short wavelengths, then somewhat less power is required
for communication at infrared wavelengths than in the microwave region.
Furthermore, a variety of parameters other than power alone may be
chosen for optimization by an extraterrestrial civilization. Hence,
while partially satisfying arguments may be given about optimal wavelengths
for a search for signals from extraterrestrial intelligence, considerable
uncertainty must remain.},

(HST STIS) spectra of the Weigelt blobs B and D, extending from 1640
to 10400 angstroms, one recorded during the 1998 minimum (1998 March)
and the other recorded in 1999 February, early in the following broad
maximum. The spatially resolved spectra suggest two distinct ionization
regions. One structure is the permanently low-ionization cores of
the Weigelt blobs B and D, located several hundred AU from the ionizing
source. Their spectra are dominated by emission from H I, [N II],
Fe II, [Fe II], Ni II, [Ni II], Cr II, and Ti II. The second region,
relatively diffuse in character and located between the ionizing
source and the Weigelt blobs, is more highly ionized with emission
from [Fe III], [Fe IV], N III], [Ne III], [Ar III], [Si III], [S
III], and He I. Through photoionization modeling, we find that the
radiation field from the more massive B-star companion supports the
low-ionization structure throughout the 5.54 yr period. The radiation
field of an evolved O star is required to produce the higher ionization
emission seen across the broad maximum. This emission region is identified
with slow-moving condensations photoionized by the O star and located
in the extended mass flow emanating from the B-star primary. Comparison
between the models and observations reveals that the high-ionization
region is physically distinct (nH approx 107 cm-3 and Te approx 104

structures that strongly scatter light, in which light waves entering
the material are scattered several times before exiting in random
directions. These randomly distributed rays interfere with each other,
leading to interesting, and sometimes unexpected, physical phenomena.
This Review describes the physics behind the optical properties of
disordered structures and how knowledge of multiple light scattering
can be used to develop new applications. The field of disordered
photonics has grown immensely over the past decade, ranging from
investigations into fundamental topics such as Anderson localization
and other transport phenomena, to applications in imaging, random

year = {2004},
pages = {711-723},
volume = {413},
abstract = {We present K-band interferometric measurements of the limb-darkened
(LD) intensity profile of the M 4 giant star psi Phoenicis obtained
with the Very Large Telescope Interferometer (VLTI) and its commissioning
instrument VINCI. High-precision squared visibility amplitudes in
the second lobe of the visibility function were obtained employing
two 8.2 m Unit Telescopes (UTs). This took place one month after
light from UTs was first combined for interferometric fringes. In
addition, we sampled the visibility function at small spatial frequencies
using the 40 cm test siderostats. Our measurement constrains the
diameter of the star as well as its center-to-limb intensity variation
(CLV). We construct a spherical hydrostatic PHOENIX model atmosphere
based on spectrophotometric data from the literature and compare
its CLV prediction with our interferometric measurement. We compare
as well CLV predictions by plane-parallel hydrostatic PHOENIX, ATLAS
9, and ATLAS 12 models. We find that the Rosseland angular diameter
as predicted by comparison of the spherical PHOENIX model with spectrophotometry
is in good agreement with our interferometric diameter measurement.
The shape of our measured visibility function in the second lobe
is consistent with all considered PHOENIX and ATLAS model predictions,
and is significantly different to uniform disk (UD) and fully darkened
disk (FDD) models. We derive high-precision fundamental parameters
for psi Phe, namely a Rosseland angular diameter of 8.13 ± 0.2 mas,
with the Hipparcos parallax corresponding to a Rosseland linear radius
R of 86 ± 3 Rsun, and an effective temperature of 3550 ± 50 K, with
R corresponding to a luminosity of \log L/Lsun=3.02 ± 0.06. Together
with evolutionary models, these values are consistent with a mass
of 1.3 ± 0.2 Msun, and a surface gravity of \log g = 0.68 ± 0.11.
Based on public data released from the European Southern Observatory
VLTI obtained from the ESO/ST-ECF Science Archive Facility. The VLTI
was operated with the commissioning instrument VINCI and the MONA
beam combiner.},

abstract = {Aims. We present line identifications in the 1700 to 10 400 Å region

The aim of this work is to characterize the behavior of these luminous,
dense gas blobs in response to the broad highstate and the short
low-state of eta Carinae during its 5.54-year spectroscopic period.
Methods. The spectra were recorded in a low state (March 1998) and
an early high state (February 1999) with the Hubble Space Telescope/Space
Telescope Imaging Spectrograph (HST/STIS) from 1640 to 10 400 A using
the 52 x 0. 1 aperture centered on Eta Carinae at position angle,
PA = 332 degrees. Extractions of the reduced spectrum including both
Weigelt B and D, 0. 28 in length along the slit, were used to identify
the narrow, nebular emission lines, measure their wavelengths and
estimate their fluxes. Results. A linelist of 2500 lines is presented
for the high and low states of the combined Weigelt blobs B and D.
The spectra are dominated by emission lines from the iron-group elements,
but include lines from lighter elements including parity-permitted
and forbidden lines. A number of lines are fluorescent lines pumped
by H Lyalpha. Other lines show anomalous excitation. Key word},

Up to two dozen lasing modes oscillate with the lasing mode rolling from the short wavelength edge to the long wavelength edge of the gain profile. The experimental results can be described very well with a set of multi–mode rate equations including self–, symmetric and asymmetric cross gain saturation. By tuning essential parameters of the gain saturation terms, mode competition disappears and single mode operation as well as mode clustering is found. This proves that the mechanisms of gain saturation have not only a profound impact on the complex temporal–spectral behavior but also explains mode clustering in (Al,In)GaN laser diodes, both in pulsed and continuous wave (cw) operation as a natural nonlinear effect without the necessity to add noise.},

The peak of the stimulated radiation falls at a lower photon energy than does the peak of the spontaneous radiation, except when T=O'K. Some numerical results are given for simple parabolic bands, specifically for the case of electron injection into p-type GaAs, and are used to deduce the temperature dependence of the forward current which is necessary to maintain a 6xed gain in the active region of a diode. The result is closely related to the temperature dependence of the threshold current in an injection laser, and gives reasonable agreement with experiment.

For many years, attempts have been made to directly measure correlations in the individual photon emission events of semiconductor lasers2,3. Previously, the temporal decay of these correlations below or at the lasing threshold was considerably faster than could be measured with the time resolution provided by the Hanbury Brown/Twiss measurement set-up4 used. Here we demonstrate a measurement technique using a streak camera that overcomes this limitation and provides a record of the arrival times of individual photons. This allows us to investigate the dynamical evolution of correlations between the individual photon emission events. We apply our studies to micropillar lasers5 with semiconductor quantum dots2,3,6,7,8 as the active material, operating in the regime of cavity quantum electrodynamics9. For laser resonators with a low cavity quality factor, Q, a smooth transition from photon bunching to uncorrelated emission with increasing pumping is observed; for high-Q resonators, we see a non-monotonic dependence around the threshold where quantum light emission can occur. We identify regimes of dynamical anti-bunching of photons in agreement with the predictions of a microscopic theory that includes semiconductor-specific effects.},

abstract = {Could a practical green laser diode finally be within sight? The latest research looks optimistic.
Researchers at the Japanese company Nichia have fabricated an InGaN semiconductor laser diode that operates at a wavelength of 515 nm and emits milliwatt-level powers in continuous-wave mode at room temperature. This news offers renewed hope that a practical commercial green laser diode may be close to fruition.
For many years, the photonics community has had access to efficient and powerful red and blue laser diodes, based on the AlInGaP and GaN material systems, respectively. These are used in a wide variety of applications, from data storage to scientific research. However, a laser diode that directly emits green light at 520–530 nm, the desired wavelength for green, has not been found. Despite intensive research, the blend of elements that has the right bandgap and supports operation at the current densities required for lasing has proved elusive.
So what is the key motivation for developing a green laser diode? As Michael Lebby, president of the Optoelectronics Industry Development Association in the US, explained in our July 2007 Technology Focus3, it offers exciting opportunities for full-colour displays and projectors that use laser diodes.
“If you have high-quality semiconductor sources of red, green and blue light and then combine that with a MEMS [microelectromechanical system] scanner, then you can make high-quality full-colour laser-based displays for mobile phones, PDAs [personal digital assistants] and televisions,” Lebby explained. “You could also make bright laser-based backlights for LCDs.” Coupled with other applications, the motivation is clear.
To get around the green laser diode problem, companies have instead used compact frequency-doubled green lasers, which use a nonlinear crystal to perform second-harmonic generation of a near-infrared laser diode. Indeed, green laser pointers and miniature colour laser projectors rely on this approach and commercial devices are widely available from firms such as Corning, Osram Opto Semiconductors and Oxxius.
“Will Nichia replicate its previous success with blue GaN laser diodes when commercializing green InGaN laser diodes?”
However, this indirect approach is not ideal for several reasons. In particular, there are limitations with efficiency, cost, the ability to miniaturize and integrate the lasers, and the capacity for mass-production. In principle, a laser diode that directly generates green light and is made entirely using well-understood semiconductor fabrication techniques would be preferable.
Nichia's latest demonstration suggests that the InGaN material, which was previously confined to operation in blue–green wavelengths below 500 nm, could indeed be the best candidate for a practical green laser diode. The prototype output power of 5 mW and estimated lifespan of several thousand hours are indeed promising for a commercial device. Furthermore, the laser was fabricated by metalorganic chemical vapour deposition (MOCVD), a well-known semiconductor fabrication technology. The challenge is now to shift operation to longer wavelengths of 520–530 nm, as 515 nm is still too short for the required green colour. Other desirable improvements are to increase the laser output power and to reduce its threshold voltage from the relatively high value of 5 V.
If successful, it is not unreasonable to wonder if Nichia may experience a case of déjà vu, with the Tokushima-based firm replicating the previous financial success that it achieved with its commercialization of blue GaN laser diodes in the early 1990s.},

The existence of such quasi Fermi levels is discussed, and it is shown that the above condition is due to the second law of thermodynamics.

The intensity correlation between the outputs of two unbalanced Mach-Zehnder interferometers (UMZIs) with two classically correlated beams of thermal light at the input exhibits genuine second-order interference with the visibility of 1/3. Surprisingly, the second-order interference does not degrade at all no matter how much the path length difference in each UMZI is increased beyond the coherence length of the thermal light. Moreover, the second-order interference is dependent on the difference of the UMZI phases. These results differ substantially from those of the entangled-photon Franson interferometer, which exhibits two-photon interference dependent on the sum of the UMZI phases and the interference vanishes as the path length difference in each UMZI exceeds the coherence length of the pump laser.

To provide a fuller discussion of coherence, a succession of correlation functions for the complex field strengths is defined. The nth order function expresses the correlation of values of the fields at 2n different points of space and time. Certain values of these functions are measurable by means of n-fold delayed coincidence detection of photons. A fully coherent field is defined as one whose correlation functions satisfy an infinite succession of stated conditions. Various orders of incomplete coherence are distinguished, according to the number of coherence conditions actually satisfied. It is noted that the fields historically described as coherent in optics have only first-order coherence. On the other hand, the existence, in principle, of fields coherent to all orders is shown both in quantum theory and classical theory. The methods used in these discussions apply to fields of arbitrary time dependence. It is shown, as a result, that coherence does not require monochromaticity. Coherent fields can be generated with arbitrary spectra.},

However, a large group of pulsating stars of intermediate mass—the so-called delta Scuti stars—have rich pulsation spectra for which systematic mode identification has not hitherto been possible6,7. This arises because only a seemingly random subset of possible modes are excited and because rapid rotation tends to spoil regular patterns8,9,10. Here we report the detection of remarkably regular sequences of high-frequency pulsation modes in 60 intermediate-mass main-sequence stars, which enables definitive mode identification. The space motions of some of these stars indicate that they are members of known associations of young stars, as confirmed by modelling of their pulsation spectra.},

Within this paper, we intend to overcome the situation by providing an introductory, neutral overview of the technology linked to lidar imaging systems for autonomous vehicles, and its current state of development. We start with the main single-point measurement principles utilized, which then are combined with different imaging strategies, also described in the paper. An overview of the features of the light sources and photodetectors specific to lidar imaging systems most frequently used in practice is also presented. Finally, a brief section on pending issues for lidar development in autonomous vehicles has been included, in order to present some of the problems which still need to be solved before implementation may be considered as final. The reader is provided with a detailed bibliography containing both relevant books and state-of-the-art papers for further progress in the subject.},

abstract = {We have built an imaging system that uses a photon's position or time-of-flight information to image an object, while using the photon's polarization for security. This ability allows us to obtain an image which is secure against an attack in which the object being imaged intercepts and resends the imaging photons with modified information. Popularly known as “jamming,” this type of attack is commonly directed at active imaging systems such as radar. In order to jam our imaging system, the object must disturb the delicate quantum state of the imaging photons, thus introducing statistical errors that reveal its activity.},

abstract = {A novel chaotic radar (CRADAR) system utilizing laser chaos is investigated both numerically and experimentally. Compared with conventional radars, the proposed CRADAR has the advantages of very-high-range resolution, unambiguous correlation profile, possibility of secure detection, low probability of intercept, and high electromagnetic compatibility. Generated by an optically injected semiconductor laser, chaotic waveforms with bandwidths larger than 10 GHz can be readily obtained. In this paper, the time series, the phase portraits, and the power spectra of the chaotic states are presented. The correlation traces between the signal and the reference waveforms are plotted. The peak sidelobe level with different correlation lengths is investigated. The capability of anti-jamming and the performance under additive white Gaussian noise are studied. To show the feasibility of CRADAR, proof-of-concept experiments using a pair of planar antennas with a 1.5-GHz bandwidth covering the range from 1.5 to 3 GHz are demonstrated. A range resolution of 9 cm is achieved, which is currently limited not by the bandwidth of the chaotic states but by the detection band},

It is natural, therefore, to explore their application to radar, despite the fact that decoherence-caused by the loss and noise encountered in radar sensing-destroys these fragile quantum properties. This article tells the story of “quantum illumination,” an entanglement-based approach to quantum radar, from its inception to its current understanding. Remarkably, despite loss and noise that destroy its initial entanglement, quantum illumination does offer a target-detection performance improvement over a classical radar of the same transmitted energy. A realistic assessment of that improvement's utility, however, shows that its value is severely limited. Nevertheless, the fact that entanglement can be of value on an entanglement-breaking channel-the meta-lesson of the quantum illumination story-should spur continued research on quantum radar.},

We use an electro-optomechanical converter to entangle microwave signal and optical idler fields, with the former being sent to probe the target region and the latter being retained at the source. The microwave radiation collected from the target region is then phase conjugated and upconverted into an optical field that is combined with the retained idler in a joint-detection quantum measurement.

abstract = {Entanglement is arguably the key quantum-mechanical resource for improving the performance of communication, precision measurement and computing systems beyond their classical-physics limits. Yet entanglement is fragile, being very susceptible to destruction by the decoherence arising from loss and noise. Surprisingly, Lloyd (2008 Science 321 1463) recently proved that a very large performance gain accrues from use of entanglement in single-photon target detection within an entanglement-destroying lossy, noisy environment when compared to what can be achieved with unentangled single-photon states. We extend Lloyd’s analysis to the full multiphoton input Hilbert space. We show that the performance of Lloyd’s single-photon‘quantum illumination’ system is, at best, equal to that of a coherent-state transmitter of the same average photon number, and may be substantially worse. We demonstrate that the coherentstate system derives its advantage from the coherence between a sequence of weak—single photon on average—transmissions, a possibility that was not allowed for in Lloyd’s work. Nevertheless, as shown by Tan et al (2008 Phys. Rev. Lett. 101 253601), quantum illumination may offer a significant, although more modest, performance gain when operation is not limited to the single-photon regime.},

abstract = {Optical intensity interferometry, developed in the 1950s, is a simple and inexpensive method for achieving angular resolutions on microarcsecond scales. Its low sensitivity has limited intensity interferometric observations to bright stars so far. Substantial improvements are possible by using avalanche photodiodes (APDs) as light detectors. Several recent experiments used APDs in single-photon detection mode; however, these either provide low electronic bandwidths (few MHz) or require very narrow optical bandpasses. We present here the results of laboratory measurements with a prototype astronomical intensity interferometer using two APDs observing an artificial star in continuous (linear) detection mode with an electronic bandwidth of 100 MHz. We find a photon-photon correlation of about 10-6, as expected from the ratio of the coherence times of the light source and the detectors. In a configuration where both detectors are on the optical axis (zero baseline), we achieve a signal-to-noise ratio of 2700 after 10 minutes of integration. When measuring the correlation as a function of baseline, we find a Gaussian correlation profile with a standard deviation corresponding to an angular half-width of the artificial star of 0.55 arcseconds, in agreement with the estimate by the manufacturer. Our results demonstrate the possibility to construct large astronomical intensity interferometers using linear-mode APDs.},

abstract = {We analyze the second-order photon autocorrelation function g(2) with respect to the photon probability distribution and discuss the generic features of a distribution that results in superthermal photon bunching [g(2)(0)>2]. Superthermal photon bunching has been reported for a number of optical microcavity systems that exhibit processes such as superradiance or mode competition. We show that a superthermal photon number distribution cannot be constructed from the principle of maximum entropy if only the intensity and the second-order autocorrelation are given. However, for bimodal systems, an unbiased superthermal distribution can be constructed from second-order correlations and the intensities alone. Our findings suggest modeling superthermal single-mode distributions by a mixture of a thermal and a lasinglike state and thus reveal a generic mechanism in the photon probability distribution responsible for creating superthermal photon bunching. We relate our general considerations to a physical system, i.e., a (single-emitter) bimodal laser, and show that its statistics can be approximated and understood within our proposed model. Furthermore, the excellent agreement of the statistics of the bimodal laser and our model reveals that the bimodal laser is an ideal source of bunched photons, in the sense that it can generate statistics that contain no other features but the superthermal bunching.},

Using stochastic multi-mode rate equations we obtain very good agreement between experiment and theory in terms of intensity profiles and intensity-correlation properties of the examined QD micro-laser's emission. Further investigations of the time-dependent emission show that super-thermal photon bunching occurs due to irregular mode-switching events in the bimodal lasers. Our bifurcation analysis reveals that these switchings find their origin in an underlying bistability, such that spontaneous emission noise is able to effectively perturb the two competing modes in a small parameter region.

abstract = {Microscale and nanoscale lasers inherently exhibit rich photon statistics due to complex light-matter interaction in a strong spontaneous emission noise background. It is well known that they may display superthermal fluctuations—photon superbunching—in specific situations due to either gain competition,leading to mode-switching instabilities, or carrier-carrier coupling in superradiant microcavities. Here we show a generic route to superbunching in bimodal nanolasers by preparing the system far from equilibrium through a parameter quench. We demonstrate, both theoretically and experimentally, that transient dynamics after a short-pump-pulse-induced quench leads to heavy-tailed superthermal statistics when projected onto the weak mode. We implement a simple experimental technique to access the probability density functions that further enables quantifying the distance from thermal equilibrium via the thermodynamic entropy. The universality of this mechanism relies on the far-from-equilibrium dynamical scenario, which can be mapped to a fast cooling process of a suspension of Brownian particles in a liquid. Our results open up new avenues to mold photon statistics in multimode optical systems and may constitute a test bed to investigate out-of-equilibrium thermodynamics using micro or nanocavity arrays.},

abstract = {Superradiance, i.e., spontaneous emission of coherent radiation by an ensemble of two-level atoms in collective states introduced by Dicke in 1954, is one of the enigmatic problems of quantum optics. The startling gist is that even though the atoms have no dipole moment they radiate with increased intensity in particular directions. Following the advances in our understanding of superradiant emission by atoms in entangled W-states we examine the quantum statistical properties of superradiance. Such investigations require the system to have at least two excitations in order to explore the photon-photon correlations of the radiation emitted by such states. We present specifically results for the spatially resolved photon-photon correlations of systems prepared in doubly excited W-states and give conditions when the atomic system emits nonclassial light. Equally, we derive the conditions for the occurrence of bunching and even of superbunching, a rare phenomenon otherwise known only from nonclassical states of light like the squeezed vacuum. We finally investigate the photon-photon cross correlations of the spontaneously scattered light and highlight the nonclassicalty of such correlations. The theoretical findings can be implemented with current technology, e.g., using ions in a linear rf-trap, atoms in an optical lattice or quantum dots in a cavity.},

abstract = {The spectral purity of an oscillator is central to many applications, such as detecting gravity waves, defining the second, ground-state cooling and quantum manipulation of nanomechanical objects, and quantum computation. Recent proposals suggest that laser oscillators which use very narrow optical transitions in atoms can be orders of magnitude more spectrally pure than present lasers. Lasers of this high spectral purity are predicted to operate deep in the ‘bad-cavity’, or superradiant, regime, where the bare atomic linewidth is much less than the cavity linewidth. Here we demonstrate a Raman superradiant laser source in which spontaneous synchronization of more than one million rubidium-87 atomic dipoles is continuously sustained by less than 0.2 photons on average inside the optical cavity. By operating at low intracavity photon number, we demonstrate isolation of the collective atomic dipole from the environment by a factor of more than ten thousand, as characterized by cavity frequency pulling measurements. The emitted light has a frequency linewidth, measured relative to the Raman dressing laser, that is less than that of single-particle decoherence linewidths and more than ten thousand times less than the quantum linewidth limit typically applied to ‘good-cavity’ optical lasers, for which the cavity linewidth is much less than the atomic linewidth. These results demonstrate several key predictions for future superradiant lasers, which could be used to improve the stability of passive atomic clocks and which may lead to new searches for physics beyond the standard model.},

abstract = {Nonclassical states are essential for optics-based quantum information processing, but their fragility limits their utility for practical scenarios in which loss and noise inevitably degrade, if not destroy, nonclassicality. Exploiting nonclassical states in quantum metrology yields sensitivity advantages over all classical schemes delivering the same energy per measurement interval to the sample being probed. These enhancements, almost without exception, are severely diminished by quantum decoherence. Here, we experimentally demonstrate an entanglement-enhanced sensing system that is resilient to quantum decoherence. We employ entanglement to realize a 20% signal-to-noise ratio improvement over the optimum classical scheme in an entanglement-breaking environment plagued by 14 dB of loss and a noise background 75 dB stronger than the returned probe light. Our result suggests that advantageous quantum-sensing technology could be developed for practical situations.},

Photon pairs are generated by spontaneous four-wave mixing, one photon from each pair (the herald) is measured locally while the other (the signal) is sent to illuminate the target. Following diffuse reflection from the target, the signal photons are detected by a receiver and nonclassical timing correlations between the signal and herald are measured in the presence of a configurable background noise source. Quantum correlations from the photon pair source can be used to provide an enhanced signal-to-noise ratio when compared to a classical light source of the same intensity.},

By the beginning of this century, scientific laboratories could produce and handle various quantum states of light: from single photons and photon pairs to squeezed states and bright twin beams. Gradually, this toolbox has become part of a range of emerging quantum technologies. The first real application of quantum optics was quantum key distribution, commercialized almost two decades ago. This is not surprising because photons are the ideal messengers and very convenient for communications as they can make use of existing optical fiber network infrastructure. A major milestone for quantum sensing is its application to new disciplines: this has excitingly been showcased by the next-generation of gravitational-wave detectors that employ squeezed light to enhance detector sensitivity; we anticipate other achievements will follow and span a huge range of disciplines, from fundamental physics to biomedicine and more. This special topic collection samples key research areas from the wider literature on quantum imaging, sensing, and spectroscopy. It also showcases developments in enabling technologies including novel nonlinear light sources as well as the growing use of enhanced CCD cameras for quantum imaging.},

abstract = {The production of pairs of entangled photons simply by focusing a laser beam onto a crystal with a nonlinear optical response was used to test quantum mechanics and to open new approaches in imaging. The development of the latter was enabled by the emergence of single-photon-sensitive cameras that are able to characterize spatial correlations and high-dimensional entanglement. Thereby, new techniques emerged, such as ghost imaging of objects — in which the quantum correlations between photons reveal the image from photons that have never interacted with the object — or imaging with undetected photons by using nonlinear interferometers. In addition, quantum approaches in imaging can also lead to an improvement in the performance of conventional imaging systems. These improvements can be obtained by means of image contrast, resolution enhancement that exceeds the classical limit and acquisition of sub-shot-noise phase or amplitude images. In this Review, we discuss the application of quantum states of light for advanced imaging techniques.},

The calibration interferometer is an equally important part of the starlight suppression system. It measures the measures the wavefront of the scattered starlight with very high SNR, to 0.05nm in less than 5 minutes on a 5mag star.

Aims. We present a modified version of the AIC not only permitting these faint companions to be detected but also their relative position to be determined with respect to the parent star, a problem that was not solved in the original design of the AIC.
Methods. In our modified design, two cylindrical lens doublets were used to remove the 180° ambiguity introduced by the AIC's original design.
Results. Our theoretical study and the numerical computations show that the axis of symmetry is destroyed when one of the cylindrical doublets is rotated around the optical axis.},

abstract = {Wide-Field Infrared Survey Telescope (WFIRST)-CGI is a NASA technology demonstration mission that is charged with demonstrating key technologies for future exo-Earth imaging missions in space. In the process, it will obtain images and low-resolution spectra of a handful to a dozen extrasolar planets and possibly protoplanetary disks. Its unprecedented contrast levels in the optical will provide astronomers' with their first direct look at mature, Jupiter-sized planets at moderate separations. This paper addresses the question: what science can be done with such data? An analytic noise model, which is informed by the ongoing engineering developments, is used to compute maximum achievable signal-to-noise ratios and scientifically viable integration times for hypothetical star–planet systems, as well as to investigate the constraining power of various combinations of WFIRST-CGI photometric and spectral observations. This work introduces two simple models for planetary geometric albedos, which are inspired largely by the solar system's gas giants. The first planet model is a hybrid Jupiter–Neptune model, which separately treats the short and long wavelengths where chromophores and methane dominate absorption, respectively. The second planet model fixes cloud and haze properties in CoolTLusty to match Jupiter's albedo spectrum, it then perturbs only the metallicity. MCMC retrievals performed on simulated observations are used to assess the precision with which planet model parameters can be measured subject to different exposure times and observing cases. Planet radius is recovered within ±15% for all observing cases with both the hybrid model and the CoolTLusty metallicity grid. Fit results for both models' parameterizations of geometric albedo spectra demonstrate that a rough indication of the metallicity or methane content should be possible for some WFIRST-CGI targets. We conclude that real observations will likely be able to differentiate between extreme cases using these models, but will lack the precision necessary to uncover subtle trends.},

Light from the off-axis source, which is exempt from destructive interference, comes out from both ports with equal intensity. The common-path scheme makes the system highly immune to environmental disturbances. In the described experiment, a 6x10power6 peak-to-peak nulling contrast was obtained.},

abstract = {WFIRST will conduct a coronagraphic program that characterizes the atmospheres of planets around bright nearby stars. When observed with the WFIRST Wide Field Camera, these stars will saturate the detector and produce very strong diffraction spikes. In this paper, we forecast the astrometric precision that WFIRST can achieve by centering on the diffraction spikes of highly saturated stars. This measurement principle is strongly facilitated by the WFIRST H4RG detectors, which confine excess charges within the potential well of saturated pixels. By adopting a simplified analytical model of the diffraction spike caused by a single support strut obscuring the telescope aperture, integrated over the WFIRST pixel size, we predict the performance of this approach with the Fisher-matrix formalism. We discuss the validity of the model and find that $10\,\mu \mathrm{as}$ astrometric precision is achievable with a single 100 s exposure of an ${R}_{{AB}}=6$ or a ${J}_{{AB}}=5$ star. We discuss observational limitations from the optical distortion correction and pixel-level artifacts, which need to be calibrated at the level of $10\mbox{--}20\,\mu \mathrm{as}$ so as to not dominate the error budget. To suppress those systematics, we suggest a series of short exposures, dithered by at least several hundred pixels, to reach an effective per-visit astrometric precision better than $10\,\mu \mathrm{as}$. If this can be achieved, a dedicated WFIRST GO program will be able to detect Earth-mass exoplanets with orbital periods of $\gtrsim 1\,\mathrm{year}$ around stars within a few pc as well as Neptune-like planets with shorter periods or around more massive or distant stars. Such a program will also enable mass measurements of many anticipated direct-imaging exoplanet targets of the WFIRST coronagraph and a "starshade" occulter.},

abstract = {Imaging planets in reflected light, a key focus of future NASA missions and extremely large telescopes, requires advanced wavefront control to maintain a deep, temporally correlated null of stellar halo i.e., a dark hole (DH) at just several diffraction beam widths. Using the Ames Coronagraph Experiment testbed, we present the first laboratory tests of Spatial Linear Dark Field Control (LDFC) approaching raw contrasts (5x10power7) and separations (1.5–5.2lambda/D) needed to image Jovian planets around Sun-like stars with space-borne coronagraphs like WFIRST-CGI and image exo-Earths around low-mass stars with future ground-based 30 m class telescopes. In four separate experiments and for a range of different perturbations, LDFC largely restores (to within a factor of 1.2to1.7) and maintains a DH whose contrast is degraded by phase errors by an order of magnitude. Our implementation of classical speckle nulling requires a factor of 2to5 more iterations and 20to50 deformable mirror (DM) commands to reach contrasts obtained by spatial LDFC. Our results provide a promising path forward to maintaining DHs without relying on DM probing and in the low-flux regime, which may improve the duty cycle of high-contrast imaging instruments, increase the temporal correlation of speckles, and thus enhance our ability to image true solar system analogues in the next two decades.},

abstract = {While the stochastic, “blinking” nature of fluorescent systems has enabled the super-resolution of their localization by the fitting of their point-spread functions (PSFs), this strategy cannot be exploited for similar resolution of “nonblinking” systems, such as those that might be encountered in a coherent Raman experiment. An alternative method for subdiffraction-limited imaging lies in the exploitation of optical heterodyning. For example, if a Gaussian PSF (a TEM00 mode) of a point emitter is displaced with respect to the origin of the optical system, photons in the higher-order TEM modes carry information about that displacement. Information concerning the displacement can be extracted from photons in these higher-order modes. These photons can be collected by optical heterodyning, which exploits the large gain in a detector’s response to an optical signal from an emitter coupled to a local oscillator, which is prepared in the TEM of interest, e.g., TEM10. We have generalized and developed the heterodyning technique to localize point emitters via the detection of higher-order spatial modes. We have developed a theoretical approach to find a practical estimation limit of the localization parameters using a realistic model that accounts for shot noise, background noise, and Gaussian noise. To demonstrate the applicability of the method, we designed experiments in which a laser is a surrogate for one and two point emitters. Using the Fisher information and its accompanying Cramér-Rao lower bound, we demonstrate super-resolution localization in these cases: we show that objects can be localized to roughly 2–3 orders of magnitude of their point-spread function’s size for a given optical system. Finally and most importantly, it is suggested that the results will ultimately be generalizable to multiple emitters and, most importantly, to “nonblinking” molecular systems, which will be essential for broadening the scope of super-resolution measurements beyond the limits of fluorescence-based techniques.},

abstract = {Spectrophotometric stability, which is crucial in the spectral characterization of transiting exoplanets, is affected by photometric variations arising from field-stop loss in space telescopes with pointing jitter or primary mirror deformation. This paper focuses on a new method for removing slit-loss or field-stop-loss photometric variation through the use of a pupil mask. Two types of pupil function are introduced: the first uses conventional (e.g., Gaussian or hyper-Gaussian) apodizing patterns; whereas the second, which we call a block-shaped mask, employs a new type of pupil mask designed for high photometric stability. A methodology for the optimization of a pupil mask for transit observations is also developed. The block-shaped mask can achieve a photometric stability of 10power5 for a nearly arbitrary field-stop radius when the pointing jitter is smaller than approximately $0.7\lambda /D$ and a photometric stability of 10power6 at a pointing jitter smaller than approximately $0.5\lambda /D$. The impact of optical aberrations and mask imperfections upon mask performance is also discussed.},

abstract = {Detecting the faint emission of a secondary source in the proximity of the much brighter one has been the most severe obstacle for using direct imaging in searching for exoplanets. Using quantum state discrimination and quantum imaging techniques, we show that one can significantly reduce the probability of error for detecting the presence of a weak secondary source, especially when the two sources have small angular separations. If the weak source has intensity relative to the bright source, we find that the error exponent can be improved by a factor of . We also find linear-optical measurements that are optimal in this regime. Our result serves as a complementary method in the toolbox of optical imaging, with applications ranging from astronomy to microscopy.},

abstract = {The wave-particle duality of light introduces two fundamental problems to imaging, namely, the diffraction limit and the photon shot noise. Quantum information theory can tackle them both in one holistic formalism: model the light as a quantum object, consider any quantum measurement, and pick the one that gives the best statistics. While Helstrom pioneered the theory half a century ago and first applied it to incoherent imaging, it was not until recently that the approach offered a genuine surprise on the age-old topic by predicting a new class of superior imaging methods. For the resolution of two sub-Rayleigh sources, the new methods have been shown theoretically and experimentally to outperform direct imaging and approach the true quantum limits. Recent efforts to generalise the theory for an arbitrary number of sources suggest that, despite the existence of harsh quantum limits, the quantum-inspired methods can still offer significant improvements over direct imaging for subdiffraction objects, potentially benefiting many applications in astronomy as well as fluorescence microscopy.},

abstract = {Characterisation of exoplanets is key to understanding their formation, composition and potential for life. Nulling interferometry, combined with extreme adaptive optics, is among the most promising techniques to advance this goal. We present an integrated-optic nuller whose design is directly scalable to future science-ready interferometric nullers: the Guided-Light Interferometric Nulling Technology, deployed at the Subaru Telescope. It combines four beams and delivers spatial and spectral information. We demonstrate the capability of the instrument, achieving a null depth better than 10power3 with a precision of 10power4 for all baselines, in laboratory conditions with simulated seeing applied. On sky, the instrument delivered angular diameter measurements of stars that were 2.5 times smaller than the diffraction limit of the telescope. These successes pave the way for future design enhancements: scaling to more baselines, improved photonic component and handling low-order atmospheric aberration within the instrument, all of which will contribute to enhance sensitivity and precision.},

title = {Spatial Linear Dark Field Control on Subaru SCExAO Maintaining High Contrast with a vAPP Coronagraph},
year = {2021},
number = {A145},
pages = {12},
volume = {646},
abstract = {Context. One of the key challenges facing direct exoplanet imaging is the continuous maintenance of the region of high contrast within which light from the exoplanet can be detected above the stellar noise. In high-contrast imaging systems, the dominant source of aberrations is the residual wavefront error that arises due to non-common path aberrations (NCPA) to which the primary adaptive optics (AO) system is inherently blind. Slow variations in the NCPA generate quasi-static speckles in the post-AO corrected coronagraphic image resulting in the degradation of the high-contrast dark hole created by the coronagraph.
Aims. In this paper, we demonstrate spatial linear dark field control (LDFC) with an asymmetric pupil vector apodizing phase plate (APvAPP) coronagraph as a method to sense time-varying NCPA using the science image as a secondary wavefront sensor (WFS) running behind the primary AO system. By using the science image as a WFS, the NCPA to which the primary AO system is blind can be measured with high sensitivity and corrected, thereby suppressing the quasi-static speckles which corrupt the high contrast within the dark hole.
Methods. On the Subaru Coronagraphic Extreme Adaptive Optics instrument (SCExAO), one of the coronagraphic modes is an APvAPP which generates two PSFs, each with a 18deg° D-shaped dark hole with approximately 10power4 contrast at lambda 1550 nm. The APvAPP was utilized to first remove the instrumental NCPA in the system and increase the high contrast within the dark holes. Spatial LDFC was then operated in closed-loop to maintain this high contrast in the presence of a temporally-correlated, evolving phase aberration with a root-mean-square wavefront error of 80 nm. In the tests shown here, an internal laser source was used, and the deformable mirror was used both to introduce random phase aberrations into the system and to then correct them with LDFC in closed-loop operation.
Results. The results presented here demonstrate the ability of the APvAPP combined with spatial LDFC to sense aberrations in the high amplitude regime (80 nm). With LDFC operating in closed-loop, the dark hole is returned to its initial contrast and then maintained in the presence of a temporally-evolving phase aberration. We calculated the contrast in 1 lambda/D spatial frequency bins in both open-loop and closed-loop operation, and compared the measured contrast in these two cases. This comparison shows that with LDFC operating in closed-loop, there is a factor of 3x improvement (approximately a half magnitude) in contrast across the full dark hole extent from 2to10 lambda/D. This improvement is maintained over the full duration (10 000 iterations) of the injected temporally-correlated, evolving phase aberration.
Conclusions. This work marks the first deployment of spatial LDFC on an active high-contrast imaging instrument. Our SCExAO testbed results show that the combination of the APvAPP with LDFC provides a powerful new focal plane wavefront sensing technique by which high-contrast imaging systems can maintain high contrast during long observations. This conclusion is further supported by a noise analysis of LDFC’s performance with the APvAPP in simulation.},

We develop an achromatic common path interferometer for observing an exoplanet (a faint off-axis source) on the background of a hoste star (bright axial source). An image of the star and its copy acquire an achromatic phase shift by 180° and interfere in antiphase. The achromatic phase shift is caused by geometric phase in the scheme of a three-dimensional interferometer. The interference process divides spatially the dark and light fields of the star image redirecting them to the opposite sides of a beam splitter. The interference process does not weaken the image of a planet, with equal intensities it is redirected to both sides of a beam splitter. The suggested scheme of common path interferometer ensures mechanical stability. The background signal is experimentally demonstrated to be reduced by six orders of magnitude.},

abstract = {The World Space Observatory for Ultraviolet (WSO-UV) is an orbital optical telescope with a 1.7-m diameter primary mirror currently under development. The WSO-UV is aimed to operate in the 115- to 310-nm UV spectral range. Its two major science instruments are UV spectrographs and UV imaging field cameras with filter wheels. The WSO-UV project is currently in the implementation phase, with a tentative launch date in 2023. As designed, the telescope field of view in the focal plane is not fully occupied by instruments. Recently, two additional instruments devoted to exoplanets have been proposed for WSO-UV, which are the focus of this paper. UVSPEX, a UV-spectrograph for exoplanets, aims to determine atomic hydrogen and oxygen abundance in the exospheres of terrestrial exoplanets. The spectral range is 115 to 130 nm, which enables simultaneous measurement of hydrogen and oxygen emission intensities during an exoplanet transit. A study of exosphere transit photometric curves can help differentiate among different types of rocky planets. The exospheric temperature of an Earth-like planet is much higher than that of a Venus-like planet because of the low mixing ratio of the dominant coolant (CO2) in the upper atmosphere of the former, which causes a large difference in transit depth at the oxygen emission line. Thus, whether the terrestrial exoplanet is Earth-like, Venus-like, or other can be determined. A Stellar Coronagraph for Exoplanet Direct Imaging (SCEDI) is aimed to directly detect the starlight reflected from exoplanets orbiting their parent stars or from the stellar vicinity including circumstellar disks, dust, and clumps. SCEDI will create an achromatic (optimized to 420- to 700-nm wavelength range), high-contrast stellocentric coronagraphic image of a circumstellar vicinity. The two instruments, such as UVSPEX and SCEDI, share common power and control modules. The present communication outlines the science goals of both proposed instruments and explains some of their engineering features.},

abstract = {The resolution of optical imaging devices is ultimately limited by the diffraction of light. To circumvent this limit, modern superresolution microscopy techniques employ active interaction with the object by exploiting its optical nonlinearities, nonclassical properties of the illumination beam, or near field probing. Thus, they are not applicable whenever such interaction is not possible, for example, in astronomy or noninvasive biological imaging. Far field, linear optical superresolution techniques based on passive analysis of light coming from the object would cover these gaps. In this Letter, we present the first proof-of-principle demonstration of such a technique for 2D imaging. It works by accessing information about spatial correlations of the image optical field and, hence, about the object itself via measuring projections onto Hermite-Gaussian transverse spatial modes. With a basis of 21 spatial modes in both transverse dimensions, we perform two-dimensional imaging with twofold resolution enhancement beyond the diffraction limit.},

The light was collected at the focal plane of a 1-m optical telescope, transported by a multi-mode optical fibre, split into two avalanche photodiodes and correlated digitally in real time. For total exposure times of a few hours, we obtained contrast values around 2 x 10e-3, in agreement with the expectation for chaotic sources, given the optical and electronic bandwidths of our set-up. Comparing our results with the measurement of Hanbury Brown et al. for a CMi, we argue for the timely opportunity to extend our experiments to measuring the spatial correlation function over existing and/or foreseen arrays of optical telescopes diluted over several kilometres. This would enable microarcsec long-baseline interferometry in the optical, especially in the visible wavelengths, with a limiting magnitude of 10.},

We introduce a novel framework to analyze a broad diversity of TS in a quantitative manner.

The Very Energetic Radiation Imaging Telescope Array System (VERITAS) Collaboration joined this program in 2018 and provides the capability to search for one particular technosignature: optical pulses of a few nanoseconds in duration detectable over interstellar distances. We report here on the analysis and results of dedicated VERITAS observations of Breakthrough Listen targets conducted in 2019 and 2020 and of archival VERITAS data collected since 2012. Thirty hours of dedicated observations of 136 targets and 249 archival observations of 140 targets were analyzed and did not reveal any signals consistent with a technosignature. The results are used to place limits on the fraction of stars hosting transmitting civilizations. We also discuss the minimum pulse sensitivity of our observations and present VERITAS observations of CALIOP: a space-based pulsed laser on board the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations. The detection of these pulses with VERITAS, using the analysis techniques developed for our technosignature search, allows a test of our analysis efficiency and serves as an important proof of principle.},

abstract = {High angular resolution observations at optical wavelengths provide valuable insights into stellar astrophysics, and enable direct measurements of fundamental stellar parameters and the probing of stellar atmospheres, circumstellar disks, the elongation of rapidly rotating stars and the pulsations of Cepheid variable stars. The angular size of most stars is of the order of one milliarcsecond or less, and to spatially resolve stellar disks and features at this scale requires an optical interferometer using an array of telescopes with baselines on the order of hundreds of metres. We report on the implementation of a stellar intensity interferometry system developed for the four VERITAS imaging atmospheric Cherenkov telescopes. The system was used to measure the angular diameter of the two sub-milliarcsecond stars beta Canis Majoris and epsilon Orionis with a precision of greater than 5%. The system uses an offline approach in which starlight intensity fluctuations that are recorded at each telescope are correlated post observation. The technique can be readily scaled onto tens to hundreds of telescopes, providing a capability that has proven technically challenging to the current generation of optical amplitude interferometry observatories. This work demonstrates the feasibility of performing astrophysical measurements using imaging atmospheric Cherenkov telescope arrays as intensity interferometers and shows the promise for integrating an intensity interferometry system within future observatories such as the Cherenkov Telescope Array.},

The technique is based on measuring interferometric photon correlations between the output ports of an asymmetric Mach-Zehnder interferometer. With this, we characterize the fraction of coherent emission in the light emitted by a laser diode when transiting through the lasing threshold.},

abstract = {The probability distribution p(n, T) of the number of counts n from a photoelectric detector illuminated by coherent light for a time T is studied, by associating photons stochastically with Gaussian random waves. The cumulants of the distribution are derived and it is shown to be of the expected form for a boson assembly in a limited volume of phase space. The distribution depends strongly on the degeneracy of the light beam. It approaches the Poisson form for classical particles at low degeneracies and the distribution characteristic of classical waves at high degeneracies. The analysis leads, incidentally, to an expression for the extent of the unit cell of phase space in the direction of the beam. It is argued that this should be adopted as the measure of coherence length.},
