Split Step Fourier Method Based Pulse Propagation Model for Nonlinear Fiber Optics

A pulse propagation model is essential to investigate various effects in nonlinear optical fiber communications. Split step Fourier method (SSFM) is an efficient technique to implement nonlinear Schrodinger equation (NLSE) which describes pulse propagation phenomenon in optical fiber. We report some simulation results obtained using our developed model based on SSFM. Our results are in well accordance with the standard results presented in the literature. We also report the effects of pre-and post-compensations to minimize pulse degradation in the presence of fiber loss, dispersion and nonlinearity. Our developed model can be used to analyze various aspects of pulse propagation in nonlinear optical fiber communications.
