Abstract

A rigorous numerical procedure is presented for the accurate characterization of optical filters incorporating two nonidentical coupled waveguides. Numerically simulated results are shown for InGaAsP/InP-based design indicating narrow bandwidth is achievable, by using waveguides with two-dimensional confinement. The numerical solution presented here also suggests that by using the multiple quantum well (MQW) region for a waveguide core the polarization dependent properties of the device can be compensated
