Applications Of Nonlinear Periodic Structures In Guided Wave Optics

Abstract

In this paper, several novel concepts are presented that relate to the propagation of light in nonlinear waveguides with a spatially periodic refractive index or boundary perturbation. The particular nonlinearity considered is an intensity-dependent refractive index. Devices based on these periodic nonlinear waveguides include variable grating couplers, optically-tunable optical filters, light controlled spatial scanners, and distributed feedback bistable optical devices. The possibility of pulse compression by nonlinear periodic structures is also considered.
