| 摘 要： | 文章基于带有各向异性完全匹配层(PML)吸收边界条件的紧凑二维频域有限差分法对八角格子光子晶体光纤(O-PCF)的模式和色散特性进行了研究.利用有效面积法分析了八角格子和六角格子光子晶体光纤(H-PCF)的基模和多模截止特性,得到非限制模、基模及多模的相图,比较发现,填充率和空气孔间距相同时,O-PCF的单模运转区域宽于H-PCF,更易用于色散补偿.

| Abstract: | On the basis of a compact two-dimensional frequency domain finite difference method with anisotropic Perfectly Matched Layers(PML) absorbing boundary conditions,the mode and dispersion properties of the octagonal Photonic Crystal Fiber(PCF) is investigated.The fundamental mode and the multimode cut-off properties of the octagonal and hexagonal PCFs are analyzed by using the effective area method and the phase diagrams of the non-finite mode,fundamental mode and multimode obtained.Their comparisons show that... |
