Refractive Index Measurements Of Planar Chalcogenide Waveguide

Abstract

We report results from a systematic study of the linear refractive index of thin films made of As - S - Se glasses which are part of the chalcogenide family. We have studied eight different compositions. The refractive index are measured by the mean of a grating coupling experiment. The measurements are performed around 1.5/μm for both annealed and non-annealed glasses. We observe that annealing the samples increases their refractive index. We also note that the increase of Selenium concentration increases the refractive index and the decrease of Arsenic concentration decreases-the refractive index.
