Stellar interferometry with a K-band integrated optics beam combiner instrument at the CHARA Array - I. First on-sky fringes for CHARIOT
Aline N. Dinkelaker, Kévin Barjot, Nic Scott +8
We present the instrument description and the first on-sky observations for the new CHara ARray Integrated Optics Testbench (CHARIOT) at the CHARA Array. CHARIOT is a 2-telescope p…
Commissioning the AIP's ultrafast laser Inscription facility: defining the parameter space for type-I waveguide fabrication
Rima Islam, Aline N. Dinkelaker, Abani Shankar Nayak +2
Astrophotonics offers a compact, stable alternative to bulk optics in traditional astronomical instrumentation, spanning high-precision spectroscopy to high-contrast interferometry…
NAIR-APREXIS: Enabling photonics-based instruments for long-baseline interferometry and integral-field spectroscopy
L. Labadie, R. J. Harris, K. Madhav +14
The NAIR project -- Novel Astronomical Instrumentation based on photonic light Reformatting -- aims at advancing photonic technologies for infrared long-baseline interferometry and…
Astrophotonic Technologies
Aline N. Dinkelaker
Over the past two decades, photonics have been developed as technological solutions for astronomical instrumentation for, e.g., near-infrared spectroscopy and long baseline interfe…
2023 Astrophotonics Roadmap: pathways to realizing multi-functional integrated astrophotonic instruments
Nemanja Jovanovic, Pradip Gatkine, Narsireddy Anugu +77
Photonics offer numerous functionalities that can be used to realize astrophotonic instruments. The most spectacular example to date is the ESO Gravity instrument at the Very Large…
Six-telescope integrated optics beam combiner fabricated using ultrafast laser inscription for J- and H-band astronomy
Aline N. Dinkelaker, Sebastian Smarzyk, Abani S. Nayak +6
We have built and characterized the first six-telescope discrete beam combiner (DBC) for stellar interferometry in the astronomical J-band. It is the DBC with the largest number of…
Astrophotonics: photonic integrated circuits for astronomical instrumentation
Martin M. Roth, Kalaga Madhav, Andreas Stoll +6
Photonic Integrated Circuits (PIC) are best known for their important role in the telecommunication sector, e.g. high speed communication devices in data centers. However, PIC also…
Simulations of mode-selective photonic lanterns for efficient coupling of starlight into the single-mode regime
Momen Diab, Aashana Tripathi, John Davenport +3
In ground-based astronomy, starlight distorted by the atmosphere couples poorly into single-mode waveguides but a correction by adaptive optics, even if only partial, can boost cou…
Ultracold atom interferometry in space
Maike D. Lachmann, Holger Ahlers, Dennis Becker +21
Bose-Einstein condensates (BECs) in free fall constitute a promising source for space-borne matter-wave interferometry. Indeed, BECs enjoy a slowly expanding wave function, display…
Starlight coupling through atmospheric turbulence into few-mode fibers and photonic lanterns in the presence of partial adaptive optics correction
Momen Diab, Aline N. Dinkelaker, John Davenport +2
Starlight corrupted by atmospheric turbulence cannot couple efficiently into astronomical instruments based on integrated optics as they require light of high spatial coherence to…
Space-borne Bose-Einstein condensation for precision interferometry
Dennis Becker, Maike D. Lachmann, Stephan T. Seidel +32
Space offers virtually unlimited free-fall in gravity. Bose-Einstein condensation (BEC) enables ineffable low kinetic energies corresponding to pico- or even femtokelvins. The comb…
