Abstract

The theoretical approach recently proposed for investigating cross-phase modulation phenomena in weakly guiding waveguides with an arbitrary cross section is revisited. The unidirectional propagation equation is reformulated so that it becomes possible to precisely investigate the evolution of the polarization state in both weakly and strongly guiding devices. For [100]-oriented AlGaAs asymmetric waveguides, it is seen that interaction between the linear and nonlinear birefringences depends on the relative position of the slow axis of the device with respect to the 45° polarization-maintaining axis in the bulk medium. The design of an AlGaAs active polarization converter with a length of 3 cm and an effective area of ∼ 6μm2 and that enables a quasi-total TE–TM conversion when using a peak power of 63 W is proposed.
