摘　　要：极化激元作为光与物质的混合激发可以实现纳米光场的精确调控,为未来纳米光电器件的小型化和集成化提供了有效的途径.近年来,借助散射型扫描近场光学显微镜对多类型极化激元的观测,多种光学现象背后的物理机制被揭示,进一步加深了对极化激元物理和相互作用的理解,也极大地推动了极化激元调控及其应用的研究.基于此,本文总结了最新的极化激元近场研究进展.不同于前期关于二维材料极化激元的综述,本文不仅涵盖了三维至一维的极化激元材料体系,还在极化激元纳米光学特性方面增添了各向异性极化激元的最新研究工作,并且系统总结了极化激元调控的最新进展以及在亚衍射成像和聚焦、纳米结构识别、光调制器和分子检测等方面的相关应用.最后,对极化激元未来的研究方向进行了展望.Polaritons,as hybrid excitations of light and matter,are important for miniaturizing the integrated nanooptoelectronic devices due to their capability of manipulating nanolight.Recently,the state-of-the-art nanoimaging technique(e.g.scattering-type scanning near-field optical microscope)has visualized various types of polaritons and revealed the physical mechanism behind them.The nanometer-resolution imaging not only deepens our understanding of fundamentals of polaritons but also promotes the studies of polariton manipulation and applications.In this review paper,we systematically summarize the recent near-field study of polaritons.Rather than other previous reviews focusing on polaritons in two-dimensional materials,our review extends the polaritonic systems to multiple dimensions(3D/2D/1D),at the same time we also collect the latest progress of polaritons in anisotropic systems.Moreover,we show the recent study of polariton manipulation and their corresponding applications,e.g.sub-diffractional imaging,focusing,optical modulator,nanostructure diagnosis and molecular sensing.Our review also look forward to future opportunities of polaritonics and its nanophotonic applications.
