| 摘 要： | 基于广义非线性薛定谔方程，利用分步傅里叶法数值模拟了超高斯时间分布的飞秒脉冲在光子晶体光纤中的传输特性。结果表明：超高斯脉冲比高斯脉冲在更短距离内形成孤子衰变，而且出现比强孤子功率稍低的次峰，孤子自频移更显著；另外，三阶色散会导致脉冲波形及频谱不对称，出现精细结构，并且有形成孤子的趋势；脉冲内拉曼散射对脉冲有平滑作用；自陡改变了主峰与次峰之间的能量分配。

| Abstract: | Based on the generalized nonlinear Schrödinger equation, the propagation characteristics of a super Gaussian femtosecond pulse in photonic crystal fibers were numerically simulated by split-step Fourier method. The result shows that soliton disintegration occured in shorter distances and soliton self-frequency shift was more remarkable for super Gaussian pulse than for Gaussian pulse, and a new lower power soliton appeared on the left side of the strong soliton. Otherwise, the 3rd-dispersion would lead to the dissymmetry and the complex structure for the pulse shape and its spectrum, and that would lead to the trend to form soliton. The pulse shape was smoothed by intrapulse stimulated Raman scattering. At the same time the energy between the two solitons was redistributed by self-ste |
