| Structure dispersion is primary when wave of input optical pulse is close to verge outside the stop-band of Fiber Bragg Gratings, optical pulse can come into being Bragg solitons by a careful control of self-phase modulation (SPM), cross-phase modulation (XPM) and group velocity dispersion (GVD). We generally take into account the linear properties about Fiber Bragg Gratings dispersion, and do not think over the effect of Fiber Bragg Gratings nonlinearity on dispersive properties.In this paper, the effects of Fiber Bragg Gratings nonlinearity on dispersive properties are studied when energy is high, and effect of nonlinearity is considered, we simulate transmission of Bragg solitons with the finite-difference scheme under the condition of nonlinear dispersion; study the effects of two kinds of dispersion... |
