方形空芯光子晶体光纤的特性分析

The characteristics analysis of square lattice hollow core photonic crystal fiber

利用全矢量有限元法,分析了方形空芯光子晶体光纤的色散特性、纤芯内的能量分布和有效模面积。结果表明,方形空芯光子晶体光纤在1.67～1.81μm范围内具有较平坦的色散特性,较高的能量分布和较大的有效模面积,为进一步设计具有平坦色散和大模场面积的方形空芯光子晶体光纤提供了理论依据和参考。

Using full-vector finite element method （FVFEM）, we analyze the dispersion, the energy distribution in the core and the effective mode area of the square lattice hollow core photonic crystal fiber. The analysis results show that the square lattice hollow core photonic crystal fiber has relatively flattened dispersion, higher energy distribution in the core and relatively larger effective mode area in the range of 1.67-1.811.1 m, which provides foundation for further design of flattened dispersion and lager mode area of square lattice hollow core photonic crystal fiber.
