Abstract

A transfer matrix method is developed for the analysis of nonlinear waveguides with Bragg gratings. In our numerical model, the nonlinear refractive-index change resulting from the optical field along a grating structure is taken into consideration. This method can be applied to the study of a wide range of nonlinear phenomena in different grating structures. We have analyzed the nonlinear responses of optical signals at the Bragg wavelength as well as other wavelengths. We show that a small change in the refractive index can cause a significant change in the optical-field distributions along the grating and also the transmission response.
