Research progress of metal halide perovskites in the preparation of nanosemiconductor lasers

As a new functional material, metal halide perovskites provide new possibilities for preparing gain media for nanosemiconductor lasers. This paper reviews the fabrication results of nanosemiconductor lasers based on metal halide perovskite materials. Firstly, three standard metal halide perovskite-based nanosemiconductor lasers are described: thin-film, nanowire, and quantum dot lasers. Under the corresponding gain structure of each laser, the appropriate gain dielectric material is discussed, and its application in the fabrication of nanosemiconductor lasers is discussed. On this basis, the effects of these gain structures and metal halide perovskite materials on the performance of nanosemiconductor lasers and related application progress are analyzed. Finally, the challenges and opportunities of nanosemiconductor lasers based on metal halide perovskite materials are summarized and the future development trend was discussed.
