近零平坦色散高非线性光子晶体光纤的研究和设计

Research and design of photonic crystal fibers with closing-zero flattened dispersion and high nonlinear

利用有效折射率法对光子晶体光纤非线性和色散进行了计算;模拟了光纤空气孔直径和孔间距对光纤特性的影响,并进行了分析;最后设计了一种零色散点在850 nm附近的近零平坦色散高非线性光子晶体光纤,这种光纤在研究光纤非线性现象时有重要的价值。

An effective index method is used to compute the nonlinear and dispersion ofphotonic crystal fibers. Then, how the air hole diameter and hole-pitch influence the properties of PCF are simulated, and the results are analysed. At last, a closing-zero flattened dispersion and high nonlinear PCF is designed, which has a zero dispersion point at 850 nm. The fiber is very useful when investigating the nonlinear properties of PCF.
