Chen Jing1, Tan Xiaoling2. Study on the mode and dispersion properties of octagonal photonic crystal fibers[J]. 2009,(2):47-49. DOI: 10.13756/j.gtxyj.2009.02.006.
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 with the same filling fraction and air hole pitch
O-PCF has wider single mode operation region and is more apt to be used for dispersion compensation than H-PCF.
