Collaborative enhancements from surface plasmons (SPs) and whispering-gallery modes (WGMs) can induce intense near-field effects with high spatial localization around the surface of a semiconducting material. One can construct a highly efficient hybrid microcavity using semiconducting materials through resonant coupling between SPs and WGMs. Hexagonal ZnO micro-/nanostructures, which have been employed as natural WGM microcavities for ultraviolet (UV) lasing, can be used as ideal platforms to construct such hybrid microcavities. Here, we comprehensively review the recent efforts for improving lasing performance by resonant coupling between SPs and WGMs. Traditional SPs originating from various metals as well as novel SPs originating from atomic layers such as graphene are considered. Moreover, we discuss the mechanism of light-matter interactions beyond the improvements in lasing performance.

表面等离激元（SP）和耳语画廊模式（WGM）的协同增强可以在半导体材料表面周围引起强烈的近场效应，并具有较高的空间局部性。通过SP和WGM之间的共振耦合，可以使用半导体材料构建高效的混合微腔。六角形的ZnO微纳米结构已被用作构建此类混合微腔的理想平台，该结构已被用作用于紫外线（UV）激光发射的天然WGM微腔。在这里，我们全面回顾了最近通过SP和WGM之间的共振耦合来改善激光性能的努力。考虑了源自各种金属的传统SP以及源自原子层（例如石墨烯）的新型SP。而且，
