提出了一种高双折射光子准晶体光纤。空气孔的十二边形Stampfli准周期晶格构成PQF的包层。通过优化纤芯周围空气孔的尺寸，使PQF在1.2 ~ 2.0 μm的宽波长范围内保持高双折射和单模工作特性。在1.31 μ m和1.55 μm光通信窗口处获得了3.86×10-2的双折射。双折射率为10-2量级，比传统保偏光纤大两个数量级，且几乎不受入射波长的影响。所提出的PQF还保持了高的非线性系数和低的限制损耗。我们的结构和模拟结果有望为相关的制造和实验提供有价值的参考和基础数据。
A photonic quasi-crystal fiber (PQF) with high birefringence is proposed. A dodecagonal Stampfli quasi-periodic lattice of air holes constitutes the cladding of the PQF. The PQF maintains the properties of high birefringence and single-mode operation regime in a wide wavelength range from 1.2 to 2.0 μm by optimizing the size of the air holes around the core of the PQF. A birefringence with 3.86×10-2 can be obtained at 1.31 and 1.55 μm optical telecommunication windows. The birefringence is of the order of 10-2, which is two orders of magnitude larger than that of the conventional polarization-maintaining fibers and hardly affected by the incident wavelength. The proposed PQF also maintains a high nonlinear coefficient and low confinement loss. Our structure and simulation results are expected to provide a valuable reference and basic data to relative fabrication and experiments.
