Paper Abstract

The design of a grating assisted directional coupler filter is outlined for a chalcogenide glass based device. The refractive index dispersion for As2Se3 is given and design equations are heuristically developed. Sensitivity analysis of these equations suggests a quick, inexpensive, and effective means to correct for the exponential sensitivity on waveguide separation in directional coupler based designs. Filter characteristics are found with the transfer matrix method and a simple tapering methodology is introduced to allow for realizable devices.
