STABILITY ANALYSIS OF NONLINEAR TE POLARIZED WAVES IN MULTIPLE-QUANTUM-WELL WAVE-GUIDES

A stability analysis of TE polarized nonlinear guided waves in multipl e-quantum-well waveguides is presented, In particular, a scalar finite element approach has been used in order to numerically investigate sy mmetrical as well as asymmetrical field distributions and their proper ties. For high input power, the analysis reveals the stable and the un stable nature of asymmetrical and symmetrical multiple quantum well wa veguide solutions. Similar features to single linear film bounded by n onlinear media are pointed out. The limits of the homogeneous slab app roximation are discussed.
