摘要
通过数值模拟双零色散波长光子晶体光纤(PCF)中超连续谱(SC)的产生，详细分析了在正常和反常色散区抽运时超连续谱的产生机理。模拟了四种不同结构参数的双零色散波长光子晶体光纤中超连续谱的产生，进而分析了两个零色散波长位置及间隔对光谱分布的影响。基于数值模拟，提出了通过优化光子晶体光纤的结构参数设计，实现控制超连续谱的谱宽和能量分布的方法。
Abstract
Supercontinuum generation (SC) in photonic crystal fibers (PCFs) with two zero dispersion wavelengths is investigated numerically, and the mechanism of SC generation in both normal dispersion region pumping and abnormal dispersion region pumping is analyzed. In order to investigate the effect of structure parameters, SC generation in four different PCFs is analyzed. And the influence of two zero dispersion wavelengths is investigated. In addition, a method for SC control on spectral width and energy distribution by designing structure parameters is proposed.
