可见光波段二维光子晶体带隙结构的理论研究
Study of Two-dimensional Photonic Crystal Band Gap in Visible Region
为了分析各种结构对二维光子晶体带隙特性的影响，本文采用高折射率材料碲化铅构建了三角、四方两种结构二维光子晶体，采用传输矩阵法对比分析了电磁波在这两类光子晶体结构中的带隙特性。计算结果表明：三角空气柱（ГK入射模式）的结构在可见光波段具有较宽的重叠带隙宽度为243nm（582～771nm）。此结构有望应用于可见光波段的光电子器件。
In this paper, photonic crystal is fabricated in a high refractive PbTe thin film. The transfer matrix method (TMM) is used to calculate the band structure of two-dimensional photonic crystal formed by the triangular and square lattice of holes in visible region. We discuss the maximization of the absolute photonic band gap width in two types of lattices. The absolute PBG has a maximum value between 582～771 nm with triangular lattice in visible region. The structure could be employed for submicron scale optoelectronic devices in the visible.
