Demonstration of simultaneous PIAA- coronagraphy and wavefront sensing using a single metasurface-based focal-plane optic
Dhwanil Patel, Sebastiaan Y. Haffert, Skyler Palatnick +23
Controlling residual wavefront aberrations downstream of an extreme adaptive optics (ExAO) system is a major challenge in high-contrast imaging. These aberrations produce quasi-sta…
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…
Millimetre-scale spectrographs for next-generation photonic instrumentation
Emily Ronson, Robert J. Harris, Ariadna Calcines Rosario +1
The paper demonstrates ultra‑compact, sub‑millimetre spectrographs printed directly onto optical fibers using two‑photon polymerisation, offering low‑mass, alignment‑free devices f…
