Photowritten high-Q cavities in two-dimensional chalcogenide glass photonic crystals
Abstract
We demonstrate a high-<em>Q</em> (∼125,000) photonic crystal (PhC) cavity formed using a postprocessing optical exposure technique where the refractive index of a photosensitive chalcogenide PhC is modified locally. The evolution of the cavity resonances was monitored in situ during writing using a tapered fiber evanescent coupling system, and the <em>Q</em> of 125,000 represents 1 order of magnitude increase over previously reported cavities in two-dimensional chalcogenide glass PhC.
