| 摘 要： | 为了研究反常色散区抽运光子晶体光纤产生的超连续谱,采用分步傅里叶方法数值模拟了飞秒激光脉冲在光子晶体光纤反常色散区中的非线性传输和超连续谱产生.结果表明,初始激光脉冲的峰值功率和脉冲初始啁啾对光子晶体光纤反常色散区产生超连续谱形状和带宽是有影响的.这些结论给光子晶体光纤中产生超连续谱提供了参考.

| Abstract: | In order to study the supercontinuum generation in a photonic crystal fiber pumped at the anomalous dispersion region, a theoretical investigation with the method of split-step Fourier is presented on the nonlinear propagation and supercontinuum generation of a femtosecond laser pulse in a photonic crystal fiber. Finally, a conclusion can be drawn that the initial pulse power and initial pulse chirp have the impact on the spectral shape and band width of the supercontinuum generation at the anomalous dispersion region in a photonic crystal fiber,which provides significant reference for supercontinuum generation in photonic crystal fibers. |
