    摘要:

    设计了一种包层为椭圆孔排列的六边形结构SF57软玻璃光子晶体光纤,在其纤芯区域引入了菱形排列的四个小椭圆孔.利用有限元法模拟了该光子晶体光纤的双折射和有效模场面积,获得了波长1.55μm处双折射为1.01×10-1,x和y偏振的有效模场面积分别为1.52μm2、1.55μm2的高双折射低有效模场面积光子晶体光纤.且对该光纤的结构参数进行了实验制作的容差性分析,得到了较大的制作容差对其光纤的双折射影响很小,具有较好的偏振稳定性.

    Abstract:

    A simple SF57 soft glass photonic crystal fiber (PCF) with a rhombic array of four elliptical holes in the core region and a hexagonal lattice of elliptical air hole cladding was proposed. The birefringence and effective mode area of the proposed PCF were studied by the full vectorial finite element method with anisotropic perfectly matched layers. A high birefringent SF57 soft glass PCF with low effective mode area has been obtained, which shows good polarization stability and large tolerance to fabrication errors. The proposed PCF has high birefringenceup to 1.01×10-1, low mode areas of 1.52μm2 and 1.55μm2 for x and y polarizations at 1.55μm.
