Abstract

A stability analysis of TE polarized nonlinear guided waves in multiple-quantum-well waveguides is presented. In particular, a scalar finite element approach has been used in order to numerically investigate symmetrical as well as asymmetrical field distributions and their properties. For high input power, the analysis reveals the stable and the unstable nature of asymmetrical and symmetrical multiple quantum well waveguide solutions. Similar features to single linear film bounded by nonlinear media are pointed out. The limits of the homogeneous slab approximation are discussed
