摘要
利用RSoft软件对包层空气孔为正六边形对称结构的光子晶体光纤的模场进行了分析,并使用模式耦合理论和传输矩阵法对光子晶体光纤光栅(PCFG)特性进行了计算和仿真,对比了不同包层结构和纤芯尺寸的PCFG反射谱之间的差异。仿真结果显示,占空比和纤芯尺寸的大小可影响谐振峰的数量和谐振波长值的大小。
The mode field of photonic crystal fibers with regular hexagonal cladding air holes is analyzed by using RSoft.The characteristics of the Photonic Crystal Fiber Grating（PCFG） are computed and simulated by using the mode coupling theory and the transmission matrix method and the differences between the PCFG reflection spectrums with different cladding structures and fiber core sizes are compared.Simulation results show that diameter-to-pitch ratio and core sizes influence the resonance peak number and the resonant wavelengths.
