摘要

文章提出一种复式矩形光子晶体结构

首先利用平面波展开法（PWM）计算这种光子晶体的能带结构

然后对结构参数值进行优化

得到较大的光子带隙。分析结果表明

当采用单晶硅作为介质柱材料时

长方晶格的晶格常数比值为0.35

.45

正方介质柱边长与长方晶格长轴比值为0.45

.50

得到的完全带隙可达到0.50

.58

完全带隙率达到近39%

这对于研制性能优良的光子晶体器件具有重要意义。

Abstract

A double-rectangular photonic crystal structure is presented.Its energy band structure is first calculated by using the Plane Wave Expansion Method（PWM） and its parameters are optimized

resulting in larger photonic bandgap.The analytical results show that when monocrystal silicon is used as the material of the dielectric cylinder

the lattice constant ratio of the rectangular lattice is in a range of 0.35

.45

the ratio between the side length of square dielectric cylinder and the major axis of the rectangular lattice is in a range of 0.45

.50.The resulted full bandgap can reach 0.50

.58 and the complete bandgap rate is close to 39%

which is of great significance for the development of photonic crystal devices with excellent performance.
