Title: First results on an electro-optic visible multi-telescope
beam combiner for next generation FIRST/SUBARU instruments
Authors: Martin, G.; Gardillou, F.; Cassagnettes, C.; Barbier, D.;
Guyot, C.; Hauden, J.; Ulliac, G.; Courjal, N.; Cvetojevic, N.; Huby,
E.; Lacour, S.
2018SPIE10701E..2VM Altcode:
Integrated optic devices are nowadays achieving extremely high
performances in the field of astronomical interferometry, as shown by
the PIONIER and GRAVITY instruments. Progress remains to be made in
order to increase the number of apertures/beams/channels to be combined
(up to 9) and eventually ensure on-chip phase modulation (for fringe
temporal scanning). We present a novel generation of beam combiners,
based on the hybridization of two integrated optic devices: (i) one
producing glass waveguides, that can ensure very sharp bend radius,
high confinement and low propagation losses, with (ii) a lithium
niobate device providing phase modulators and channel waveguides that
can achieve on-chip, fast (<100kHz) phase modulation. The aim of
this work is to compare three different concepts for the new generation
FIRST/SUBARU 9T instrument, in terms of transmission, birefringence,
half-wave voltage modulation and spectral range.

Title: SWIFTS: on-chip very high spectral resolution spectrometer
Authors: le Coarer, E.; Venancio, L. G.; Kern, P.; Ferrand, J.; Puget,

2017SPIE10565E..1BL Altcode:
The size and the weight of state of the art spectrometers is a serious
issue regarding space applications. SWIFTS (Stationary Wave Integrated
Fourier Transform Spectrometer) is a new FTS family without any moving
part. This very promising technology is an original way to fully
sample the Fourier interferogram obtained in a waveguide by either a
reflection (SWIFTS Lippmann) or counter-propagative (SWIFTS Gabor)
interference phenomenon. The sampling is simultaneously performed
the optical path thanks to "nano-detectors" located in the evanescent
field of the waveguide. For instance a 1.7cm long waveguide properly
associated to the detector achieves directly a resolution of 0.13cm-1
on a few centimetre long instruments. Here, firstly we present the
development status of this new kind of spectrometers and the first
results obtained with on going development of spectrometer covering
simultaneously the visible domain from 400 to 1000 nm like an Echelle
spectrometer. Valuable technologies allows one to extend the concept to
various wavelength domains. Secondly, we present the results obtained
in the frame of an activity funded by the European Space Agency where
several potential applications in space missions have been identified
and studied.

Title: Novel multi-telescopes beam combiners for next generation
instruments (FIRST/SUBARU)
Authors: Martin, G.; Pugnat, T.; Gardillou, F.; Cassagnettes, C.;
Barbier, D.; Guyot, C.; Hauden, J.; Huby, E.; Lacour, S.
2016SPIE.9907E..38M Altcode:
Integrated optic devices are nowadays achieving extremely good
performances in the field of astronomical interferometry, as shown by
PIONIER or GRAVITY silica/silicon-based instruments, already installed
at VLTI. In order to address other wavelengths, increase the number
of apertures to be combined and eventually ensure on-chip phase
modulation, we are working on a novel generation of beam combiners,
based on the hybridization of glass waveguides, that can ensure very
sharp bend radius, high confinement and low propagation losses, together
with lithium niobate phase modulators and channel waveguides that can
achieve on-chip, fast (<100kHz) phase modulation. The work presented
here has been realized in collaboration with our technological partners
TeemPhotonics for glass waveguides and iXBlue-PSD for lithium niobate
phase modulators. We will present our results on a hybrid glass/niobate
(passive/active) beam combiner that has been developed in the context
of FIRST/SUBARU 9T beam combiner. The combiner is structured in three
parts: a) the first stage (passive glass) achieves beam splitting from
one input to eight outputs, and that for nine input fibers coming
from the sub-apertures of the Subaru telescope; b) the second stage
consists on a 72 channel waveguides lithium niobate phase modulator in a
push-pull configuration that allows to modify on-chip the relative phase
between the 36 pairs of waveguides; c) a final recombination system of
Y-junctions (passive glass) that allows to obtain combination of each
input to every other one. The aim of this presentation is to discuss
different issues of the combiners, such as transmission, birefringence,
half-wave voltage modulation and spectral range.

We first recall observational facts related to the properties of the
F layer and to the airglow in the intertropical region. We establish
the relationship between the intensity of the red line on one side and
f<SUB>0</SUB>F and h<SUB>F' </SUB> on the other side. The formula is
used for discussing properties of the two zones of increased emission
of radiation 6300 Å located on both sides of the magnetic equator.

Title: Observations of the Aurora Borealis
Authors: Barbier, D.; Williams, D. R.
1950JGR....55..401B Altcode:
From spectrograms obtained near Fairbanks, Alaska, identifications
of lines and bands in the spectral range from 3100Å to 5000Å are
proposed. The presence of the heretofore debatable lines, NI 3467 and
OI 4368, is confirmed. The observed intensity distribution in the
Vegard-Kaplan system in the aurora is entirely different from that
in the night sky. Several weak spectrograms in the region 6300Å to
6900Å are discussed. Visual observations of auroral phenomena are
set forth and include a detailed description of a blue, sunlit aurora.

Title: Photometric studies of the light of the night sky.
Authors: Roach, F. E.; Barbier, Daniel
1949AJ.....54..193R Altcode:
An automatic recording photoelectric photometer for scanning the night
sky has been in operation at Cactus Peak near Inyokern, California,
for several months. Observations are made through interference filters
which isolate either EO i~ 5577 or Na 1 5893. The general background
of starlight and zodiacal light is recorded by use of a control filter
which excludes the emission line. The heights in the upper atmosphere
to the emitting layers are deduced from zenith to horizon observations
making allowance for the unsymmetrical intensity of the sky. We have
found for EO i~ 5577 a height of about 100 km and for Na 1 5893 a height
of about 300 km. The sodium D emission has been followed in the late
twilight (solar depression 180 to 450) Interpreting the observations as
a resonance phenomenon we have found that, in the 200 to 600 km region
of the upper atmosphere, the distribution of sodium atoms corresponds
to a scale height of 250 km as compared with about 10 km in the 70 to
100 km region. A detailed report will appear in the TransaclIons of
Ihe American Geophysical Union. This work is supported by the Office
of Naval Research. Pasadena, Calsj.

M. E. Esclangon, Director of the observatory Paris, publishes the
following observations made at Paris observatory (Equatorial of the
Carte du Ciel; observers: de Grandchamp, Canavaggia, Mineur, Barbier;
computers: Mineur, Canavaggia, Barbier): 1930 U.T. R.A. (1930.0)

Prof. Shapley: "Leuschner telegraphs preliminary investigation Lowell
observatory object by Bower and Whipple results in group of solutions
giving approximate present distance forty one astronomical units
inclination 17 deg. longitude node 109 deg. Observations chiefly
by Meyer Lick Observatory March 16th to April 4th are accurately
represented by orbits varying from near circle to parabola with
perihelion distance 17 astronomical units." An Observation Circular from
the Lowell Observatory of 1930 March 13 gives details about the search
for a transneptunian planet, the discovery of the new object on plates
of 1930 Jan. 21, 23 and 29 and about the observations since that time.
