A particular photonic crystal fiber (PCF) designed with all circle air holes is proposed. Its characteristics are studied by full-vector finite element method (FEM) with anisotropic perfectly matched layer (PML). The simulation results indicated that the proposed PCF can realize high birefringence (up to 10(-2)), high nonlinearity (50W(-1)·km(-1) and 68W(-1)·km(-1) in X and Y polarizations respectively) and low confinement loss (less than 10(-3)dB/km at 1.55um wavelength).
提出了一种设计有全圆形气孔的特殊光子晶体光纤（PCF）。采用具有各向异性完全匹配层（PML）的全矢量有限元方法（FEM）对其特性进行了研究。模拟结果表明，所提出的光子晶体光纤可实现高双折射（高达10^(-2)）、高非线性（在X和Y偏振中分别为50W^(-1)·km^(-1)和68W^(-1)·km^(-1)）以及低限制损耗（在1.55μm波长处小于10^(-3)dB/km）。
