摘　　要：光学微腔通过在介观尺度上增强光与物质相互作用,可作为通用功能结构用于增强荧光辐射与拉曼散射过程,在痕量物质检测、光电发光器件等领域具有独特的优势。随着微纳加工技术的不断进步,光学微腔的设计朝着更高品质因子和更小模式体积方向发展,光与物质相互作用效率持续提升,展现出了更多独特的光辐射及光散射增强特性。然而,相比于金属表面等离激元近场调控,光学微腔在增强荧光及拉曼痕量检测方面仍面临挑战。为了克服这一难题,人们提出了光学微腔-金属/二维半导体复合结构,为不同场景下的高性能荧光增强和拉曼痕量检测提供了全新的解决方案,展现出光学微腔在光辐射和光散射增强领域巨大的应用潜力。本文总结了近20年来光学微腔荧光和拉曼光谱增强技术的研究进展,详细介绍了光学微腔的种类及其光学特性,深入探讨了光学微腔及其复合结构荧光和拉曼增强机制与前沿研究成果。最后,对未来光学微腔荧光和拉曼光谱增强技术的发展和应用前景进行了总结与展望。Optical microcavities highly confine optical fields in microscales to boost the interaction strength between photons and matters,which can be used as a general structure for enhancement of florescence and Raman scattering in applications of trace-detection and optoelectronics.The development of nanomanufacturing techniques advances optical microcavities to higher quality factors and smaller mode volumes,by which several new physical phenomena in radiation and scattering processes are observed.Unfortunately,the performance of optical microcavities in fluorescence and Raman enhancement competitive to surface plasmonic resonances supported by metallic nanostructures is still challenging.The hybrid structures integrating optical microcavities with metals or 2D materials are therefore proposed,opens up new opportunities to boost the microcavity-enhanced radiation and inelastic scattering superior to traditional surfaceenhanced fluorescence and surface-enhanced Raman spectroscopy in a variety of applications.This article reviews the advancements in optical microcavity enhanced fluorescence and Raman spectroscopies over past two decades.It provides a comprehensive overview of the types and optical properties of optical microcavities,and deeply explores the enhancement mechanisms in the cutting-edge of the related studies.Finally,the prospects of optical microcavity enhanced fluorescence and Raman spectroscopy in development and future applications are summarized.
