摘要：

In this paper, we propose a novel high birefringent terahertz (THz) photonic crystal fiber (PCF) with subwavelength circular air hole pairs in the core which are arranged as a hybrid crystal lattice structure. And its high mode birefringence is realized by reducing structure symmetry in core. A professional software COMSOL Multiphysics 4. 0 is used for modeling, and the simulation results show that this kind of THz PCF exhibits a high birefringence on a level of 10(-2) and low confinement loss over a wide THz frequency range. Moreover, the birefringence or confinement loss can be controlled flexibly by adjusting some fiber parameters. Compared with a similar structure PCF for the optical communication, the THz PCF is easier to practically fabricate, owing to its large wavelength size.
