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…
Comparative analysis of fiber Bragg grating filter losses inscribed by continuous wave UV and femtosecond-IR lasers for astrophotonics
Aashia Rahman, Ria G. Krämer, Abani Shankar Nayak +8
Fiber Bragg grating (FBG) filters have been demonstrated as promising components in astrophotonic instrumentation for near-infrared ground-based observations. Given the photon-star…
Qualification pathways for Photonic Integrated Circuits in Astrophotonic Space Missions
Kalaga Madhav, Aashia Rahman, Máté Ãdámkovics
Photonic integrated circuits (PICs) promise order-of-magnitude reductions in the size, weight and power (SWaP) of optical subsystems for astronomy, planetary and Earth-observation…
Information limits of photonic lantern wavefront sensing: a Fisher- and quantum-Fisher-information framework and its relation to Fourier-filtering sensitivity limits
Kalaga Madhav
The photonic lantern is an all-photonic wavefront sensor native to single-mode-fibre-fed instruments, but its performance is almost always quoted through a specific reconstruction…
Scaling laws for multi-object spectrographs: empirical relationships and the photonic advantage of CAWSMOS
Kalaga V. Madhav, Martin M. Roth
The paper analyzes how the mass and cost of multi‑object spectrographs scale with the number of channels and resolving power, and shows that photonic integrated‑circuit designs lik…
Towards a Comprehensive Understanding of Planetary Systems through Population-Level, Large-Scale Surveys
Francisco J. Pozuelos, Pedro J. Amado, Jesús Aceituno +13
Over the past three decades, exoplanet research has delivered an extensive census of planets spanning a wide range of masses, sizes, and orbital configurations. Despite this progre…
