Abstract: When the interaction between excitons and cavity photons is stronger than the decay of excitons and cavity photons, a strong coupling occurs between exciton energy level and cavity mode, thereby generating the quasi-particles called exciton-polaritons. The small effective mass and strong nonlinearity of exciton-polariton make it great potential in the applications of slow light and low-power-consumption light emission devices. However, weak exciton binding energy of traditional III-V inorganic semiconductor materials and weak nonlinearity of organic semiconductor materials limit their application of exciton-polaritons at room temperature. In contrast, halide perovskites have a series of excellent photoelectric properties such as high absorption coefficient, long diffusion length, high defect tolerance, and low rates of nonradiative recombination. Furthermore, with large exciton binding energy and oscillator strength, halide perovskites become an ideal material for studying strong interaction between light and matter. The research progress on exciton-polaritons based on the strong coupling between halide perovskite and Fabry-Pérot (F-P) microcavities was introduced from two aspects: the structure kinds of halide perovskites and the type of F-P microcavities. Firstly, the research background of polaritons and the basic photoelectric properties of halide perovskites were reviewed. Secondly, the respective characteristics of three-dimensional perovskites and two-dimensional layered perovskites and related research on strong coupling with F-P microcavities were introduced. Afterwards, the regulation and application of self-organized and non-self-organized F-P microcavities to perovskite exciton-polaritons were discussed. Finally, the challenges and future research directions of halide perovskite exciton-polaritons were summarized and prospected.
