Abstract: Based on the generalized nonlinear SchrSdinger equation,we investigate efficient dispersive wave (DW) generation in a photonic crystal fiber (PCF) by numerical simulation and discuss a way to control DW generation by using an initial input pulse chirp.It is shown that efficient red-shifted DW generation can be obtained in a PCF with negative dispersion slopes.The energy contained in the DWs is considerably decreased for both positively and negatively chirped pulses at the fiber output.This provides us with an opportunity to conveniently and efficiently manipulate the DW generation by controlling the pre-chirp of the soliton.Moreover,we also show that forthand higher-order dispersion terms play little part in deciding the evolution of DWs.
