摘要
利用有限差分束传播法分析全内反射型光子晶体光纤(PCF),研究了PCF基模有效折射率和纤芯附近功率分布随PCF结构参数变化的关系,初步探讨了空气孔参数的扰动对光纤模式的影响。所得结果为PCF的设计制作提供参考。
The scalar finite element based beam propagation method(FD-BPM) is applied to analyze the total internal reflection(TIR)based photonic crystal fibers(PCF).The effects of the number of holes and the geometrical parameters of the TIR-PCF on the effective index,the power distribution of the fundamental mode near the core area have been studied.The effects of the cross-section geometry perturbations on the effective index have been discussed.
