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飞秒脉冲在光子晶体光纤中的传输情况,并与皮秒脉冲进行了比较。当初始脉宽小于1 ps时高阶效应对脉冲传输的影响将不可忽略。在此基础上,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 femtosecond gauss pulse in photonic fibers numerically, by split-step Fourier method. When the initial GaUss pulse width less than 1 ps, high order nonlinear effect in fiber communication must be considered. By simulating and analyzing the change of compression factor, quality factor, peak power of compressed pulse and optimal fiber length, some valuable comclusions are obtained. Gauss pulse with various central wavelength compression can be attained in photonic crystal fibers.
