In an attempt to develop a streamlined astrophotonic instrument, we demonstrate the realization of an all-photonic device capable of both multimode to single mode conversion and spectral dispersion on an 8-m class telescope with efficient coupling. The device was a monolithic photonic spectrograph which combined an integrated photonic lantern...
Photonic technologies offer numerous advantages for astronomical instruments such as spectrographs and interferometers owing totheir small footprints and diverse range of functionalities. Operating at the diffraction-limit, it is notoriously difficult to efficientlycouple such devices directly with large telescopes. We demonstrate that with...
We demonstrate for the first time an efficient, photonic-based astronomical spectrograph on the 8-m Subaru Telescope. An extreme adaptive optics system is combined with pupil apodiziation optics to efficiently inject light directly into a single-mode fiber, which feeds a compact cross-dispersed spectrograph based on array waveguide grating...
