摘要
从麦克斯韦方程组出发,利用有限元方法,分析光子晶体光纤的色散特性。在考虑纯石英材料自身色散的前提下,计算光子晶体光纤的模场分布,基模有效折射率和色散系数等参数。结果表明,调节空气孔直径d和包层空气孔间距∧的大小,改变空气孔填充介质的折射率n,可以有效地控制光子晶体光纤的色散,为光子晶体光纤的设计和制造提供了理论依据。
Based on Maxwell equations and using the finite element method （FEM）, the dispersion of photonic crystal fiber is investigated. Furthermore, the parameters including model field distribution, effective refractive index of fundamental mode, and dispersion are calculated on the premise of the pure quartz material self chromatic dispersion. The results suggest that the dispersion of PCF can be controlled by adjusting the diameter （d） of air hole, the distance between cladding air holes, and the refractive index （n） of stuffing medium. These results provide the theoretical base for the design and production of the photonic crystal fiber.
