Paper Abstract

This paper presents a study of the nonlinear wave propagation in an adiabatic all-optical switch, which is composed of an asymmetric Y-branch ion-exchanged glass waveguide with a strip of nonlinear polymer loaded on top of one branch. By extending the effective index method to the analysis of the nonlinear waveguides, the nonlinear dispersion curves are calculated at the successive sections to illuminate the evolution of the normal modes in the device. To further demonstrate the nonlinear switching behaviors in the Y-branch waveguide, a beam propagation method is also employed to simulate the optical field propagation. The inputs by three different ports are investigated.
