Aplicação da técnica de programação reversa na transmissão de um Pulso Gaussiano via fibra óptica.

Abstract

Digital Back-Propagation (DBP) is a promising technique to compensate nonlinear distortions in optical communications systems, focusing mainly on the Nonlinear Schr¨odinger Equation and the Split-Step Fourier Method. This report describes, after a theoretical review, a numerical simulation of this technique, using MATLABR , applied to a chirped Gaussian pulse emitted by a laser source that propagates through the optical fiber, with the intent of analyzing its effectiveness and limitations. Until recently, compensation of linear and nonlinear impairments were processed separately. DBP comes as a versatile and universal technique to jointly compensate both kinds of distortions.
