提出了一种在光子晶体光纤中实现单偏振单模（SPSM）工作的新设计，采用了两排三个中心空气孔放大的矩形晶格光子晶体光纤。提出的光子晶体光纤是完全由二氧化硅材料的各向异性完全匹配层的全矢量有限元法建模。通过调节中心放大空气孔的大小，可以自由调节单偏振区的位置。利用这种结构，一个SPSM光子晶体光纤的限制损耗小于0.1 dB/km的波长范围内从1.20到1.66妈妈和有效模面积约5.9 mum 2在1.55妈妈已成功地设计。所提出的光纤是一种非线性SPSM，它可能适用于非线性光学应用或具有宽SPSM工作带宽要求的应用
The present paper proposes a novel design for achieving single-polarization single-mode (SPSM) operation in photonic crystal fiber (PCF), using a rectangular-lattice PCF with two lines of three central air holes enlarged. The proposed PCF that is composed entirely of silica material is modeled by a full-vector finite element method with anisotropic perfectly matched layers. The position of the region of single polarization can be tuned freely by adjusting the size of the central enlarged air holes. Using this structure, an SPSM PCF with confinement loss less than 0.1 dB/km within the wavelength range from 1.20 to 1.66 mum and effective mode area about 5.9 mum2 at 1.55 mum has been successfully designed. The proposed fiber is a nonlinear SPSM, which may be useful for nonlinear optical applications or applications with a wide SPSM operating bandwidth requirement
