给出了描述掺杂的一维光子晶体结构缺陷态的变化规律及其空间局域度特性的理论表达式.该式对由具有任意色散关系材料组成的、中间掺杂、两边对称的一维光子晶体结构均成立.通过研究含奇异材料的光子晶体组态发现,当缺陷层材料为右手材料时,光子带隙中缺陷态的频移方向随缺陷层厚度的增大而红移;当缺陷层材料是左手材料时,频移方向刚好相反,表现为蓝移.该缺陷态的空间局域度只与两边对称结构有关.两边对称结构含奇异材料的光子晶体的缺陷态比传统右手材料的结构具有更强的空间局域度.
The theoretical expression of the variation law of defect states of the one-dimensional photonic crystal doped with one-dimensional photonic crystal and its local characteristic of the space are given. The formulas of two-dimensional photonic crystal with one-dimensional The photonic crystal structures are established.Studying the configuration of photonic crystal with strange material, it is found that when the defect layer material is right-handed material, the frequency shift of the defect state in the photonic bandgap shifts red with the increase of defect layer thickness. When the layer material is left-handed material, the direction of frequency shift is just the opposite, which shows a blue-shift. The spatial localization of the defect state is only related to the symmetrical structures on both sides. The defect states of the photonic crystals containing the singular material on both sides of the symmetry structure are lower than that of the conventional right-handed material Structure has a stronger spatial locality.
