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…
Empirical verification of principal mode orthogonality and relative phase calibration in photonic lanterns
Adam K. Taras, Barnaby R. M. Norris, Christopher Betters +6
Photonic lanterns efficiently map input spatial modes to single-mode outputs for applications like high angular resolution imaging and nulling interferometry. However, manufacturin…
