Abstract

A novel approach, based on a scalar-corrected formalism, is proposed for investigating cross-phase modulation phenomena in waveguides with arbitrary cross sections. The proposed approach is applied to investigate the evolution of the polarization state in asymmetric angle-facet AlGaAs rib waveguides. It is seen that the orientation of the optical axes of the waveguides should be a determining parameter in optimizing the power transfer between the polarization modes and that asymmetric angle-facet AlGaAs rib waveguides could be promising devices for application in all-optical switching.
