Simulation and Applications of Nonlinear Fiber Bragg Gratings

Abstract:- We have simulated the behaviors of nonlinear fiber Bragg gratings (FBGs). The generalized nonlinear equations governing these structures are solved by a method which uses a Fourier series procedure and a simple iterative method. All of the nonlinear effects are considered. Bragg soliton generation in intrinsic media and birefringence effects in FBGs are studied. We found that the first order dispersion can causes time shifting in the input pulse peak. It is shown that FBGs are proper for optical switching too. They can use in filters, nonlinear fiber optical applications, soliton propagations etc
