Abstract

A computer-aided technique, based on the finite element method, has been developed for analyzing intensity-dependent properties of TE waves guided by multiple-quantum-well (MQW) waveguides with arbitrary nonlinear media. Self-consistent solutions are obtained by a simple iterative procedure. The numerical results for TE power-dependent modes are presented for waveguides with either linear or nonlinear cladding regions. They reveal that, for values of total optical power above a certain threshold, the effect of nonlinear cladding regions on the propagation characteristics can be ignored. The power-dependent behavior of a non-Kerr-like case is also examined.<>
