Abstract
A variety of components are now available for constructing photonic circuits for signal switching and manipulation. Combining an intensity-dependent refractive index with gratings produces bistable feedback structures.1 Nonlinear self-induced polarization effects in waveguides give polarization rotation and switching.2 In this paper we combine the three phenomena: grating, birefringence, and nonlinearity. An abrupt transition from linear to nonlinear behavior is then obtained in waveguides with birefringent gratings.
