Polarization dependent leakage loss as well as optical birefringence for the fundamental mode in square- and rectangular-lattice holey fibers with elliptical air holes are studied numerically based on the full-vector finite element method for the first time. It is shown that high birefringence in the order of 10-2 and large polarization dependent loss required for single-polarization single-mode transmission are both achievable by using the proposed structure.
首次基于全矢量有限元方法对具有椭圆形气孔的方形和矩形晶格多孔光纤中基模的偏振相关泄漏损耗以及光学双折射进行了数值研究。结果表明，通过使用所提出的结构，可以实现10^-2量级的高双折射以及单偏振单模传输所需的大偏振相关损耗。
