随着后摩尔时代的到来, 对大容量、高速度信息处理的需求使得半导体器件应用由电子集成转向光子集成, 高性能微纳激光器是实现光子集成的重要环节. 种类丰富的半导体材料促进了半导体微纳激光器的快速发展, 近年来, 随着大量新型半导体材料(如二维半导体、铅卤钙钛矿等)的涌现, 有望实现半导体微纳激光器性能的进一步提升. 由于钙钛矿材料具有高光吸收、缺陷高容忍、激子结合能大等优异光学性质, 使其成为高增益、低阈值半导体微纳激光器的优秀候选材料. 法布里-珀罗(F-P)谐振腔激光器是钙钛矿激光器中研究广泛、结构简单、应用价值较高的一类激光器. 本文以铅卤钙钛矿F-P谐振腔激光器为例, 对其工作机理以及近年来的研究成果进行综述, 从激子与光子弱耦合的光子激光和强耦合的极化子激光两个方面出发, 详细介绍了钙钛矿材料既作为增益介质又作为谐振腔的F-P结构激光器以及仅作为增益介质的F-P腔激光器的激光的产生原理和影响因素, 最后总结了钙钛矿F-P谐振腔激光器当前面临的挑战, 展望了其进一步发展可能具备的前景.With the advent of the post-Moore era, the demand for large-capacity and high-speed information processing has caused the application of semiconductor devices to shift from electronic integration to photonic integration. High-performance micro-nano lasers are an important part of achieving photonic integration. Varieties of semiconductor materials have promoted the rapid development of semiconductor micro-nano lasers. In recent years, with the advent of a large number of new semiconductor materials (such as two-dimensional semiconductors, lead halide perovskites, etc.), it is expected that the performances of semiconductor micro-nano lasers will be further improved. Perovskite materials have excellent optical properties such as high light absorptions, high defect tolerances, and large exciton binding energy, which make them excellent candidate materials for high-gain, low-threshold semiconductor micro-nano lasers. The Fabry-Perot (F-P) resonator laser is a type of perovskite laser with extensive research, simple structure and high application value. In this paper, we take lead halide perovskite F-P resonator laser for example, and summarize its working mechanism and recent research results, by starting from two aspects of photon laser with exciton and photon weak coupling and strong coupling polariton laser. And we introduce the lasing principle and influencing factors of F-P structure lasers with perovskite materials as both gain medium and resonant cavity and F-P cavity lasers with perovskite as only gain medium in detail. Finally, the current challenges of perovskite F-P resonant lasers are summarized, and the possible prospects of its further development are also presented.
