摘 要
首先概述了光子品体的根本理论以及开展，然后运用传输矩阵方法算出一维缺陷光子品体内缺陷模的局域场强分布，结论显示缺陷位置两边分布是低折射率的介质层的构形禁锢光的本领不如两边是高折射率的本领强。维持缺陷位置光学厚度一定的情况下，缺陷位置折射率相对于其双侧的折射率愈小，光局域本领也就愈强。当缺陷位置两旁是高折射率的介质时,所探讨的光子品体构形与出现共振米散射与布拉格散射前提相符时,相对局域化长度能获得最低值。最后简述了光子局域化的应用。

Abstract
First outlined the basic theory and the development of photonic crystals, and then using the transfer matrix method to calculate one-dimensional photonic crystal defects in local field intensity distribution of defect modes, the conclusion shows that the localization of photons in the structure with a defect layer bordering on high refractive index layers on both sides of the defect layer is stronger than that bordered on low refractive index layers. Maintain the defect position optical thickness certain cases, On both sides of the defect location index relative to its refractive index is smaller, the photon localization is stronger. When the defect layer borders on high refractive index layers on both of its sides, and if both the resonance Bragg scattering and the resonance Mie scattering conditions are satisfied, the relative localization length can get the lowest. Finally briefly photon localization applications.
Key words: photonic crystal; localization; defect mode; relative localization length.
