摘要光子晶体是一种由具有不同折射率的介质按照周期性排列方式组成的光学结构体，其介电常数在空间结构中的排布也呈周期性，是一种人工制造的微型结构。因为这种人工制造的微型结构类似于晶体的“周期性结构”，故称之为光子晶体。30641
光子晶体微腔是光子晶体的一种特别的形态，其具有限制光子传播的特性，而这种特性的应用范围也非常广，如新型光子晶体光纤等。
本文是利用软件Rsoft对光子晶体进行模型建立并仿真，然后得到能量分布线图和脉冲频谱图等，并将单缺陷和去除七个空气孔的光子晶体微腔进行比较，对比其在相同激励下其各自的能量分布以及特点，分析其工作环境中的优劣，而通过观察和对文献的阅读，验证了去七空气孔的光子晶体微腔结构在实际应用中较具有单缺陷的光子晶体微腔更具优势。
文章最后,我们根据得到的结论并结合查阅所得知识，总结出了光子晶体微腔的结构对性质的影响。

Title Design and characteristics of photonic crystal micro-cavities
Abstract
Photonic crystal is a kind of artificial micro optical structure which has different refractive index of the medium in accordance with the periodic arrangement. Because of this artificial micro structure is similar to the "crystal periodic structure", it is called a photonic crystal.
Photonic micro-crystal is a special form of photonic crystal, which has the characteristics of limiting the photon propagation, and the application of this characteristic is also very wide, such as the new type of photonic crystal fiber, etc.
This paper uses software Rsoft photonic crystal modeling and simulation, and then we can get the energy distribution curve and pulse frequency spectrum, then we compare the single defective photonic crystal micro-cavities and removal of seven air holes photonic crystal micro-cavities by comparing to their respective energy distribution and characteristics under the same incentive to analyze the work environment.Through observation and reading of literature we verify the removing seven center air holes photonic crystal micro-cavity structure compared with single defect photonic crystal micro-cavity inpractical application has more advantages.
In the end, based on the conclusion and relevant knowledge, we can sum up the impact of the structure of photonic crystal on it’s properties.
