摘要

提出一种基于复式三角晶格的红外光子晶体光纤

该光纤采用具有优良透过特性的Ge30Sb8Se62硫系玻璃作为基底材料

由圆形与方形两种介质柱组成晶格

两者按横、纵向上错位相间嵌套排列

每个介质柱与相邻介质柱的夹角都成60°。文章采用平面波展开法和有限元法分析了不同结构下该光纤的光子带隙和限制损耗特性

通过优化光纤的结构参数

获得了10.6μm处大带隙、低损耗的光子晶体光纤。

Abstract

This paper proposes a compound triangular lattice-based infrared photonic crystal fiber.This fiber uses chalcogenide glass Ge30Sb8Se62 with good transmittance as the substrate material.The lattice consists of circular and square dielectric cylinders

which are horizontally and vertically dislocated in an interphase nested arrangement and every two adjacent cylinders are inclined to each other at 60°.This paper analyzes the photonic bandgap and limit loss characteristics of the fiber in different structures by using the plane wave expansion method and the finite element method and obtains a large bandgap and low-loss photonic crystal fiber at 10.6μm by optimizing the structural parameters of the fiber.
