摘　　要：利用等离激元纳米光腔将电磁场限制在亚波长范围,可在纳米尺度上增强光与物质相互作用,实现超衍射极限的光信号增强。从等离激元纳米光腔的基本原理出发,综述了等离激元纳米光腔与量子发射体间相互作用的理论框架,分析了不同光腔结构在增强光与物质耦合作用的优势;归纳了纳米光腔增强光与物质相互作用机制,着重讨论了增强拉曼光谱、增强非线性效应和增强量子效应的物理机制;展望了等离激元纳米光腔在量子信息领域的潜在应用。Plasmonic cavities can limit the electromagnetic field to the sub-wavelength range and enhance the interaction between light and matter at the nanoscale,leading to optical signal enhancement under the ultra-diffraction limit.Based on the basic principle of the plasmonic cavities,the review introduces the theoretical framework of the interaction between the plasmonic cavities and the quantum emitter,as well as the structure of plasmonic cavities,in order to reveal its advantages of enhancing the interaction of light-matter.Then the plasmonic cavities enhancing the coupling of light and matter from weak to strong is summarized,the advanced research works of surface enhanced Raman scattering and tip enhanced Raman scattering is also introduced.In addition,the physical mechanisms and applications of plasmonic cavity enhancing nonlinear and quantum plasmonic are discussed.Finally,the potential application of the plasmonic cavities in the field of quantum information is prospected.
