提出了一种矩形晶格单偏振单模光子晶体光纤的设计方案。建议的光纤研究完全匹配层的全矢量有限元法。该光纤在一定波长范围内实现了单偏振单模工作区，包括1.55 μm波长。在1.55 μm波长处，一个偏振态的损耗为0.124dB/km，另一个偏振态的限制损耗很高，不能保证光纤的传输。单偏振单模光子晶体光纤在高功率光纤激光器、光纤陀螺、电流传感器和光相干通信系统等偏振敏感领域有着广泛的应用前景。
A design for single-polarization single-mode photonic crystal fiber with rectangular lattice is proposed in this paper. The proposed fiber is studied by the full vector finite element method with perfectly matched layers. The single-polarization single-mode operation region of the fiber is achieved in a certain wavelength range with low confinement loss include the wavelength of 1.55 μm. The loss of one polarization is 0.124 dB/km at the wavelength of 1.55 μm and the confinement loss of the other one polarization is very high which can not ensure the transmission in the fiber. The single-polarization single-mode photonic crystal fiber is desirable for some polarization-sensitive applications such as high-power fiber lasers, fiber optic gyroscopes, current sensors and optical coherent communication systems.
