Nanophotonics and meta-optics based on optically resonant all-dielectric structures is a rapidly developing research area driven by its potential applications for low-loss efficient metadevices. Recently, the study of halide perovskites has attracted enormous attention due to their exceptional optical and electrical properties. As a result, this family of materials can provide a prospective platform for modern nanophotonics and meta-optics, allowing us to overcome many obstacles associated with the use of conventional semiconductor materials. Namely, the perovskites provide simple and cheap wet-chemistry methods of nanofabrication, high quantum yield and pronounced excitonic properties at room temperature, broadband and reversible spectral tunability, high defect tolerance, high enough refractive index for light confinement at subwavelength scale, as well as flexibility regarding integration with various nanophotonics designs. Here, we review the recent progress in our research of halide perovskite nanophotonics starting from single-particle light-emitting nanoantennas [1,2,3] and nano/micro-lasers [4,5] to the large-scale designs working for surface coloration, anti-reflection, optical information encoding, and enhanced solar energy harvesting [6].
