高双折射的混合格子太赫兹光子晶体光纤的设计与研究
Design and study of high birefringent terahertz photonic crystal fiber with hybrid crystal lattice
摘要
Abstract
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 10-2and 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.关键词
