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

摘要： 光子灯笼（PL）是一种新型设备，能够高效地将多模光纤转换为若干单模光纤。 当与极端自适应光学（ExAO）系统和光谱仪结合时，PLs 能够实现高角分辨率的高通量光谱学。 最近，位于昴宿星望远镜的 Subaru Coronagraphic Extreme 自适应光学（SCExAO）系统获得了一个 PL，它可以将其多模输入转换为 19 个单模输出。 这些单模输出馈送到优化用于 600 至 760 纳米波长范围的 R~4,000 光谱仪中。 本文介绍了 PL 在 SCExAO 上的集成，并从通过率、视场和光谱重建的角度研究了该设备的性能。 我们还展示了首个可见光 PL 与 ExAO 系统耦合的天文观测演示，与单独使用单模光纤相比，其通量提高了 12 倍。 这项工作为未来在小角分辨率下的高通量光子仪器铺平了道路。 显示英文摘要

摘要： 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 and a spectrograph, PLs enable 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 of view, and spectral reconstruction. We also present the first 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.
