Visible Photonic Lantern integration, characterization and on-sky testing on Subaru/SCExAO

Sébastien Vievard, Manon Lallement, Sergio Leon-Saval +23

A Photonic Lantern (PL) is a novel device that efficiently converts a multi-mode fiber into several single-mode fibers. When coupled with an extreme adaptive optics (ExAO) system a…
