金属卤化物钙钛矿材料具有溶液可加工性、低成本、载流子迁移率大且平衡、高光学增益和带隙可调等优点，在相干光源领域具有广阔的应用前景。随着材料合成和纳米纤维技术的快速发展，钙钛矿激光器已经实现了各种成分，形貌，尺寸，大小，激发方案和腔配置，从而产生不同的发射特性。本文系统地综述了钙钛矿激光器模式控制的最新进展，包括发射波长、模式数、方向、偏振和轨道角动量等。提出并讨论了控制排放的策略的有效性评价标准。最后，提出了钙钛矿激光器模式控制的挑战和趋势。
Metal halide perovskites, as promising photovoltaic materials, have shown great potential in coherent light sources due to their unprecedented properties, such as solution processability, low cost, large and balanced carrier mobility, high optical gain, and tunable bandgap. With the rapid development in the material synthesis and nanofabrication technique, perovskite lasers have been realized in a variety of compositions, morphologies, dimensions, sizes, excitation schemes, and cavity configurations, giving rise to distinct emission characteristics. In this perspective, the latest progress in the mode control over perovskite lasers, including emission wavelength, mode number, direction, polarization, and orbital angular momentum, is systematically reviewed. Criteria for evaluating the effectiveness of the strategies to steer the emission are proposed and discussed. Lastly, the challenges and trends for the mode control of perovskite lasers are presented.
