中文摘要： 半导体微腔是微纳光学中操纵光子的核心器件之一，而光子反聚束是量子通信器件单光子源的理论基础，所以研究基于半导体微腔的单光子源具有重要应用价值。本项目拟从理论上研究半导体微腔中激子极化激元的模式剪裁与反聚束效应，主要内容如下：拟利用周期和缺陷光栅等微纳结构，剪裁微腔光学模式，进而剪裁激子极化激元模式；通过模式剪裁增强激子极化激元非线性相互作用和量子干涉效应，从而提高其反聚束性能；拟结合激子极化激元的外场响应，研究其反聚束行为与模式剪裁和外场的物理关系。方法上，拟采用多模耦合转移矩阵理论和有限元模拟，研究不同微纳结构对微腔光学模式和激子极化激元模式的剪裁性能；拟采用量子主方程和关联函数，研究激子极化激元的量子相干性和反聚束效应，并确定反聚束条件。鉴于Ⅲ-Ⅴ族氮化物量子材料具有较大激子束缚能（如GaN量子阱约为40 meV），所以预计本项目能够实现工作在室温的半导体微腔单光子源。

英文摘要： Semiconductor microcavity is one of key device manipulating photons in micro/nano-photonics, and photon anti-bunching is the theoretical basis of single photon source in quantum communication, so it is of great value to study the single photon source based on semiconductor microcavities. The present project aims at theoretically studying the mode tailoring and anti-bunching effects of exciton polaritons in semiconductor microcavities. Main contents of the present project are as follows. Micro/nano-structures, such as periodical or defected lattices, are used to tailor the optical modes of microcavities and the corresponding exciton polariton modes. By the mode tailoring, we study how to enhance the nonlinear interaction and quantum interference effects between exciton polaritons, and how to improve the anti-bunching behavior of exciton polaritons. Combining the response of exciton polaritons on the applied fields, we plan to study the physical relations of the exciton-polariton anti-bunching behavior with the mode tailoring and applied fields. In calculation, multi-mode coupled transfer matrix and finite element simulation will be used to study the tailoring effects of the different micro/nano-structures on the microcavity optical modes and exciton polariton modes.
