Abstract

A Photonic Lantern (PL) is a novel device that efficiently co nverts a mu lti-mode fib er int o sev eral single-mode fibers. W hen c oupled w ith a n e xtreme a daptive o ptics (ExAO) s ystem a nd a s pectrograph, P Ls e nable high throughput spectroscopy at high angular resolution. The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) system of the Subaru Telescope recently acquired a PL that converts its multi-mode input into 19 single-mode outputs. The single mode outputs feed a R 4,000 spectrograph optimized for the 600 to 760 nm wavelength range. We present here the integration of the PL on SCExAO, and study the device performance in terms of throughput, field o f v iew, a nd s pectral r econstruction. We a lso p resent t he fi rst on -sky demonstration of a Visible PL coupled with an ExAO system, showing a significant improvement of x12 in throughput compared to the use of a sole single-mode fiber. This work paves the way towards future high throughput photonics instrumentation at small angular resolution.
