Miniaturized lasers with high spectra purity and switchable output are of crucial importance for various ultracompact photonic devices. However, it still remains a great challenge to simultaneously control the wavelength and mode purity of microscale lasers due to the insensitive response of traditional materials to external stimuli. In this work, we propose a strategy to realize switchable single-mode microlasers in perovskite microwires (MWs) coupled with responsive organic microdisk cavities. The perovskite MW therein serves as an excellent laser source to deliver multiple lasing modes, while the microdisk functions as a spectral filter to achieve single-mode outcoupling. Furthermore, on account of the sensitive responsiveness of organic materials, reversible wavelength-switching of single-mode laser can be realized through adjusting the resonant modes of the microdisk cavity filter. The results will provide guidance for the rational design of nanophotonic devices with novel performances based on the characteristic of organic materials.

响应式有机微盘调制的可切换单模钙钛矿微激光

具有高光谱纯度和可切换输出的微型激光器对于各种超紧凑型光子器件至关重要。然而，由于传统材料对外部刺激的不敏感反应，同时控制微尺度激光器的波长和模式纯度仍然是一个巨大的挑战。在这项工作中，我们提出了一种在钙钛矿微丝（MWs）中结合可响应的有机微盘腔体来实现可切换单模微激光的策略。其中的钙钛矿MW用作提供多种激光模式的出色激光源，而微盘则用作实现单模输出耦合的光谱滤波器。此外，由于有机材料的敏感性，通过调节微盘腔滤光片的谐振模，可以实现单模激光器的可逆波长切换。研究结果将为基于有机材料特性的具有新颖性能的纳米光子器件的合理设计提供指导。
