Abstract

We present a Computer Aided Design model of a polymer directional coupler and show some preliminary comparision of the predicted characteristics with characteristics of directional couplers fabricated in a side-chained PMMA/DR1. This model encompasses many of the physical processes and effects encountered in the manufacture of passive polymer directional couplers, including actual transverse index profile induced by bleaching, longitudinal variations in the effective index of the polymer due random variations in the material, and the coupling between wave guides in the s-bend transition region of the directional coupler.
