Abstract

It is shown that the finite difference method may be extended to study the propagation characteristics of optical waveguides whose cross-sections contain regions of complex local refractive index, representing gain or loss. Complex propagation constants are calculated for a range of stripe geometry laser structures and compared with those obtained from other methods. When used in conjunction with a simultaneous finite difference solution of the carrier rate equation, the complex optical waveguide method provides a powerful self-consistent laser model
