Characterization and on-sky testing of photonic, AWG-based astronomical spectrographs
Jeronimo Calderon-Gomez, Frantz Martinache, Nick Cvetojevic +14
The paper presents the characterization of arrayed‑waveguide grating (AWG) photonic chips and their on‑sky testing with a high‑resolution near‑infrared spectrograph prototype, demo…
Overcoming the low signal-to-noise problem for hybrid mode-selective photonic lantern-based wavefront correction using machine learning
Nathan K Long, Barnaby Norris, Daniel S Dahl +10
Hybrid mode-selective photonic lanterns transform an input complex point-spread function into several single-mode outputs, where a selected core feeds the fundamental mode to a pho…
Seidr update: photonic 'black magic' for high-contrast interferometry using kernel-nulling and photonic lanterns
Nathan K Long, Daniel S Dahl, Christopher H Betters +13
Seidr is a new interferometric beam combiner within the Asgard Suite, utilizing infrastructure common to the BIFROST instrument at the Very Large Telescope Interferometer. Seidr co…
