摘　　要：在忽略光纤损耗情况下,运用分布傅立叶方法数值模拟了皮秒脉冲在光子晶体光纤中的传输情况.计算分析了初始啁啾对脉冲压缩的影响,通过分析脉冲压缩比、品质因子、峰值功率比和最佳光纤长度的变化,得出了一些有意义的结论.As the fiber loss is neglected the effect of initial chirp on the propagation of picosecond gauss pulse in photonic fibers numerically,by split-step Fourier method.By simulating and analyzing the change of com- pression factor,quality factor,peak power of compressed pulse and optimal fiber length,we reach some valua- ble conclusions.Gauss pulse with various central wavelength compression can be attained in photonic crystal fi- bers.
