Paper Abstract

This paper begins with a brief description of the nonlinear Schroedinger equation (NLSE). Then split-step Fourier transform method (SSFT) is used to simulate the pulse evolution when high order group dispersion and high order nonlinear effect are considered. Different phenomena induced by high order group dispersion are discussed, where the effect of the polarity of the pulse chirp, the third-order dispersion coefficient, and the effect of the high-order dispersion on self-phase modulation (SPM) are also discussed, respectively. For the high power density in the wavelength diversion multiplexing (WDM) system, some phenomena induced by high-order nonlinearity such as self-steepening are simulated, and qualitative analysis is given at the same time.
