| 摘 要： | 为了研究光子晶体光纤结构参数对非线性系数及色散特性的影响,采用全矢量等效折射率模型,进行了理论分析,研究发现,通过调节结构参数可以灵活设计波长在820nm附近具有较大非线性系数和较低色散值的高非线性色散平坦光子晶体光纤。结果表明,高非线性色散平坦光子晶体光纤的研究前景十分可观。

| Abstract: | In order to analyze the dependence of the nonlinear coefficient and dispersion property on the structural parameters of photonic crystal fibers,a vector effective index model was used.Through analyzation,it is possible to design photonic crystal fibers with high nonlinear coefficient and nearly zero dispersion at wavelengths of around 820nm.Results show that there are huge potential in photonic crystal fibers of high nonlinear flattened dispersion. |

| Keywords: | fiber optics nonlinearity flattened dispersion nonlinear coefficient photonic crystal fiber |
