Analyses of Dispersion Properties of Photonic Crystal Fibers with Regular Hexagonal Cladding Air Holes

介绍了光子晶体光纤的特点和分类。为了进一步分析塑料光子晶体光纤中各参数对塑料光子晶体光纤色散性能的影响,利用RsoftCAD软件中的Fullwave模块对不同参数的塑料光子晶体光纤进行模拟计算,通过时域有限差分(FDTD)法对包层空气孔为六边形的塑料光子晶体光纤色散特性进行分析,给出了塑料光子晶体光纤色散特性随孔间距、孔大小等参数变化的一般规律。通过对塑料光子晶体光纤的包层结构进行多组比较,以便为实际塑料光子晶体光纤的制作与研发提供理论依据。

In this paper the characteristics and the classification of photonic crystal fibers （PCF） are introduced. In order to analyze the influence of different parameters on the dispersion properties of plastic PCF, the Fullwave modules of the software RsoftCAD is used to simulate the plastic PCF with different parameters. According to the principle of finite-difference time-domain （FDTD）, the dispersion properties of photonie crystal fibers with hexagonal cladding air holes are analyzed. The variation rules of the dispersion properties with both space and size of air holes and so on have been given. The multi-grouped comparisons of the cladding structure of PCF would provide more theoretical basis for the further exploration and fabrication of actual plastic PCF.
