Chalcogenide glass photonic crystals: Progress and prospects

Abstract

In this review, we discuss the progress and prospects offered by chalcogenide glass photonic crystals. We show that by making photonic crystals from a highly-nonlinear chalcogenide glass, we have the potential to integrate a variety of active devices into a photonic chip. We describe the testing of two-dimensional Ge33As12Se55 chalcogenide glass photonic crystal membrane devices (waveguides and microcavities). We then demonstrate the ability to not only post-tune the devices properties but also create high Q cavities by using the material photosensitivity. Show more
