Abstract

The impact photonic technologies have had, and continue to have, on astronomical interferometry are considerable and wide-ranging. Microscopic waveguide structures that coherently rout starlight are combined with other photonic components into `photonic chips', which can perform a myriad of functions useful to interferometry, such as beam combination, routing, and active phase control. Here we will highlight the exploits of existing photonic technologies active and in development on telescopes around the world, the many state of the art prototype devices in various stages of on-sky testing, and some exciting novel photonic technologies just beyond the horizon.
