Empirical verification of principal mode orthogonality and relative phase calibration in photonic lanterns

Adam K. Taras, Barnaby R. M. Norris, Christopher Betters +5

The paper experimentally characterizes the principal modes of a photonic lantern using digital off‑axis holography, showing they are highly orthogonal and proposing ways to use thi…

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…

Illuminating the lantern: coherent, spectro-polarimetric characterisation of a multimode converter

Adam K. Taras, Barnaby R. M. Norris, Christopher Betters +4

While photonic lanterns efficiently and uniquely map a set of input modes to single-mode outputs (or vice versa), the optical mode transfer matrix of any particular fabricated devi…
