中文摘要： 表面等离激元与半导体微腔的耦合将改变微腔的模式特性，并调控半导体微腔中激子极化激元的单光子与双光子自发辐射特性。本项目将研究微腔中激子极化激元与表面等离激元的耦合规律，研究该耦合对微腔模式的影响，分析该耦合对激子极化激元的自发辐射的调控规律。项目同时将研究表面等离激元在整个可见光波段内对微腔模式的影响，分析耦合的色散规律。项目还将分析从紫外到整个可见波段范围内表面等离激元耦合对半导体微腔品质因子的影响。项目的另一研究重点是研究表面等离激元耦合对微腔中激子极化激元双光子自发辐射的调控规律及其模式分布，特别是双光子辐射的偏振与单光子辐射偏振的关系。分析研究耦合强度对双光子辐射效率的影响，确定双光子辐射效率与等离激元耦合的关系。本项目的研究成果在亚波长光电子领域有广泛的应用前景，将丰富人们对等离激元与半导体微腔耦合规律的认识。

The project will investigate the coupling of the plasmon polariton in the microstructure of semiconductor microcavity/dielectri layer/metal, analyze the eigen modes of the exciton polariton with different coupling of the plasmon polariton. The focus of this research is the effect of the coupling intensity with the change of the dielectric layer thickness.The project will investigate the coupling effect of the plasmon polariton on the microcavity modes in the whole visible waveband and analyze the dispersion of the coupling. The project will determine the microcavity modes with different coupling of the plasmon polariton in the whole visible waveband. This project will also investigate the quality factor of the microcavity with the coupling of the plasmon polariton from the violet to visible waveband.In the above investigations, theoretical researches with the finite element met
