摘要 通过引入包层有效折射率的概念定义了光子晶体光纤中模式激发的判断条件;使用有限元法精确求得了光子晶体光纤的包层有效折射率和有效模折射率的数值解;给出了不同波长的光在不同结构光子晶体光纤中的模场分布,其结果与实验图样一致。 Judgement for mode-exciting of photonic crystal fiber is denned by introducing cladding-effective-index. Using a finite element method, cladding-effective-index and effective mode-index are accurately calculated, and mode distributions in different photonic crystal fiber of various wavelength light are given, the results are consistent with the experiments.
