摘　　要：为更精细地描绘飞秒光脉冲在光子晶体光纤中的传输和演化,在用分步傅里叶方法求解广义非线性薛定谔方程的基础上,详细考虑光纤参数随脉冲峰值频移的变化,模拟了飞秒光脉冲在光子晶体光纤中传输和演化的过程。研究发现,光纤色散和强非线性对飞秒脉冲在光子晶体光纤中传输、演化以及超连续谱的展宽有很大影响。In order to describe the evolvement and transmission of a femtosecond laser pulse in a photonic crystal fiber subtly, the variation of frequency corresponding to peak pulse power is considered adequately, on the basis of solving generalized nonlinear Schroedinger equation by split-step Fourier method. The process of the evolvement and transmission is numerically stimulated. It is found that its evolvement, transmission and band width of the supercontinuum are affected greatly by dispersion of the photonic crystal fiber and the strong nonlinear property.
