摘　　要：纳米激光器在光通信、全息技术、生物医疗成像等领域有着广泛的应用前景。表面等离激元(Surface plasmon polariton,SPP)沿着金属表面传播,基于该特性可制成突破衍射极限的低阈值纳米激光器。它们不但具有小尺寸特征,同时还能激发Purcell效应,表现出更高的自发辐射效率。近年来,金属-绝缘体-半导体(MIS)波导结构的SPP激光器因具有超强的模式约束能力被大量报道。本文以基于MIS结构的SPP激光器为主题进行综述。首先,介绍了SPP激光器的工作原理,接着分别介绍了基于MIS波导结构的纳米片型和纳米线型SPP激光器的工作原理。然后,依据增益介质材料的不同,依次介绍了增益介质分别为Ⅱ-Ⅵ半导体、Ⅲ-Ⅴ半导体以及钙钛矿的SPP MIS波导激光器研究进展。最后,总结全文,并对基于MIS波导的SPP激光器未来的发展和挑战进行了展望。Micro-lasers have wide application prospects in optical communication,holographic technology,biomedical imaging and other fields.Surface plasmon polariton(SPP)propagates along the metal surface,which can be used to fabricate low-threshold nanolasers that break the diffraction limit..They not only have the characteristic of small size,but also can induce the Purcell effect,so that the spontaneous emission efficiency can be significantly enhanced.In recent years,SPP lasers based on metal-insulator-semiconductor(MIS)waveguide structures have attracted much attention because of their ability of extremely large mode constraint.In this paper,SPP lasers based on MIS waveguide structures will be reviewed.Firstly,the basic mechanism of SPP laser is introduced,and the working principles of nanoplatelet type and nanowire type SPP lasers based on MIS waveguides are introduced respectively.Then,according to different gain medium materials,this paper introduces the research progress of SPP MIS waveguide lasers whose gain media areⅡ-Ⅵsemiconductor,Ⅲ-Ⅴsemiconductor and perovskite respectively.Finally,the thesis is summarized,and the future development and challenges of SPP MIS waveguide lasers are prospected.
