摘　　要：利用COMSOL Multiphysics软件进行仿真,计算了光子晶体光纤不同掺杂半径下,导波基模有效折射率的分布,并与传统光纤相比,得出表现光子晶体光纤特性的最佳掺杂半径大小范围。分析了非线性系数受掺杂半径的影响,为更好地设计光子晶体光纤光栅提供理论依据。By using COMSOL Multiphysics, This paper obtains the distribution of fundamental mode effective index with different radius of doped core ofphotonic crystal fiber. Comparing with the step-index fiber, the paper presents the range of doped core radius which can perform the best characteristics of photonic crystal fiber. The influence of doped core radius on nonlinear parameter is analyzed, which provides theoretical evidence to better design the photonic crystal grating.
