Abstract

This paper presents a study of the nonlinear waves and bistabilities in multilayer waveguide systems and all-optical switch with self-focusing media. In terms of Jacobian elliptic functions, the dispersion relations for TE modes in the nonlinear multilayer waveguide are derived analytically. The analyses show that the bistabilities can be obtained with power thresholds in 4 and 5 layer waveguide structures. The characteristics of the nonlinear waves and power- dependent field profiles in the multilayer waveguide systems are illustrated by numerical calculations and possible applications to all-optical devices are also discussed. Furthermore, with extending these knowledges to the analyses of the Y-branch adiabatic all-optical switch, the device nonreciprocal properties are fully investigated as well as demonstrated by simulations of the finite difference beam propagation method (FD-BPM).
