Abstract
The main goals of astrophotonics are to miniaturize astronomical instrumentation and improve its performance [1]. Photonic technologies allow to channel, manipulate, and disperse light in an efficient and cost-effective way. The photonic platform of guided light in fibers and waveguides has opened the doors to next-generation instrumentation for both ground- and space-based telescopes in the optical and near/mid-IR bands. I will describe photonic devices developed for spectral filtering, spectroscopy, and interferometry that provide capabilities beyond the reach of conventional astronomical instruments. I will also discuss promising avenues of research, based on anticipated improvements in the fabrication methods and photonic technologies.
