Abstract

In recent years photonic technologies have had a major impact on astronomy. Astrophotonics now includes the use of photonic chips to perform coherent pupil remapping, beam splitting and combination, and nulling. The high stability and precise tolerances intrinsic to astrophotonic devices make them especially useful in interferometry, where maintaining coherence is critical. Both laser direct write chips (ideal for 3D to 2D pupil remapping) and photolithographic devices (ideal for complex beam combination systems) have seen recent successes. Here some of the various astrophotonic technologies applicable to interferometry will be outlined, and the current state of the art and future steps with the technology will be discussed.
