Highly Birefringent Photonic Crystal Fibers Based on Micro-hole-structured Fiber Core
基于小圆孔结构纤芯的高双折射光子晶体光纤

A method by employing circular micro holes in the fiber core was proposed to achieve highly birefringent photonic crystal fibers(PCFs).The birefringence property of highly birefringent PCFs was investigated by employing a full-vector finite-element method(FEM) and anisotropic perfectly matched layers.The relationship between the birefringence and the number,diameter and distance of the circular holes in the fiber core was discussed.A PCF with birefringence up to an order of 10-2 was designed.Simulation resu...
