Abstract

A convenient, reliable and fast computation scheme for evaluating the carrier induced change in the optical propagation characteristics in semiconductor rib waveguide structures is presented. The modes of the unperturbed waveguide are computed by the Spectral Index Method while Perturbation analysis is used to evaluate the modal characteristic following barrier injection. Macroscopic carrier transport equations combined with appropriate approximations provide the basis for obtaining almost analytic solutions for the injected carrier profile. The modeled operational characteristics of injection current controlled deep ridge waveguide couplers are presented to illustrate the attractive features of this computational scheme.
