The performance of optical transmission system, which operates at data rates above 10 Gb/s is limited by fiber nonlinearity and group velocity dispersion (GVD). In this paper we have solved the nonlinear Schrodinger equation analytically using Volterra series for studying the impact of self-phase modulation (SPM) and GVD only on direct detection fiber-optic transmission system. In the anomalous dispersion...
The dynamics of nonlinear pulse propagation in optical fibers is governed by the famous nonlinear Schrodinger equation (NLSE), in which the group-velocity dispersion and self-phase modulation form a basic set of optical processes describing a broad range of realistic physical situations. In this work, by means of variational formalism for the NLSE, we derive exact analytical expressions for the variational...
