摘要 运用分步傅里叶方法数值模拟了飞秒高斯脉冲在光子晶体光纤中的传输,计算分析了初始啁啾对脉冲压缩效应的影响。结果表明,初始啁啾有利于增强压缩效果,提高脉冲压缩质量和峰值功率,但使得最佳光纤长度减小。选取合适的光纤长度,可有望对各种波长的脉冲进行压缩。 A theoretical investigation by split-step Fourier method is presented on the propagation of a femtosecond Gauss pulse in photonic crystal fibers. The effect of initial chirp on pulse compression is simulated and analyzed. It is found that compression factor, compression quality factor and peak power increase with initial chirp, while optimal fiher length decreases. If an appropriate optical fiber length is selectod, efficient pulse with various central wavelength eomoression can be attained in Dhotonic crystal fibers.
