混合金属卤化物钙钛矿（MHP）已显示出卓越的光电性能以及简便且具有成本效益的可加工性。随着MHP太阳能电池和发光二极管的成功，MHP也表现出作为片上激光器增益介质的巨大潜力。然而，迄今为止，光泵浦MHP激光器和电驱动MHP激光器的稳定运行-MHP激光器插入芯片级光子集成电路的基本要求-尚未得到证明。主要的障碍包括MHP在大气中的不稳定性，初步的MHP激光腔图案化方法，以及对MHP材料和腔中的发射机制的理解不足。本文旨在提供一个详细的概述不同的策略，以提高在大气中的MHP的固有特性，并建立一个最佳的MHP腔图案化方法。此外，本文还讨论了MHP材料和腔体中不同的发射机制以及如何区分它们。
Hybrid metal‐halide perovskites (MHPs) have shown remarkable optoelectronic properties as well as facile and cost‐effective processability. With the success of MHP solar cells and light‐emitting diodes, MHPs have also exhibited great potential as gain media for on‐chip lasers. However, to date, stable operation of optically pumped MHP lasers and electrically driven MHP lasers—an essential requirement for MHP laser's insertion into chip‐scale photonic integrated circuits—is not yet demonstrated. The main obstacles include the instability of MHPs in the atmosphere, rudimentary MHP laser cavity patterning methods, and insufficient understanding of emission mechanisms in MHP materials and cavities. This review aims to provide a detailed overview of different strategies to improve the intrinsic properties of MHPs in the atmosphere and to establish an optimal MHP cavity patterning method. In addition, this review discusses different emission mechanisms in MHP materials and cavities and how to distinguish them.
