摘要：

采用矢量波束传播法(BPM) 对不同结构参量的光子晶体光纤的色散和非线性特性进行数值分析,计算色散平坦光子晶体光纤的参量色散系数D,有效模场面积和非线性系数。分析D, 与色散平坦光子晶体光纤结构参量空气孔间距、空气孔直径之间的关系。分析结果表明,调节色散平坦光子晶体光纤的结构参量可以灵活地调整色散和非线性特性。得到的色散平坦光子晶体光纤在1300nm到1600nm波长范围内,色散值仅在-1.5 左右,非线性系数都大于19 。

Abstract:

The dispersion and nonlinear property of dispersion flattened photonic crystal fibers(PCF) with different structural parameters were numerically analyzed using beam propagation method.We calculated dispersion coefficient D, effective mode area and nonlinear coefficient .We analyzed the relationship between D, and pitch , hole diameter d. The results indicate that dispersion and nonlinear property of dispersion flattened photonic crystal fiber can be controlled by the structural parameters , d .In the range from 1300nm to 1600nm, PCF’s dispersion achives about -1.5 ,non-linear cofficient is above 19.

Key words: nonlinear optics, photonic crystal fiber, beam propagation method, dispersion, nonlinear coefficient
