Paper Abstract

A self-consistent computer analysis of beam propagation in a twin-ridge waveguide coupler with distributed gain is presented. The structure is assumed to be fabricated in double heterostructure material which is electrically pumped to provide the gain. Non-linear coupling between the ridge-guides occurs because of the effects of lateral carrier diffusion and stimulated recombination on the lateral complex refractive index profile of the structure. The paper uses the beam propagation method to examine the longitudinal development of the optical field distribution in the coupler for a range of injection current densities.
