摘　　要：微纳激光器是一类尺寸或模式体积在波长或亚波长尺度的小型化激光器,由于其在超灵敏化学、生物传感和片上光信息的产生、传输、处理等领域具有重要应用而备受关注.有机材料来源广泛、吸收与发射截面大,有利于产生高的光学增益,为构筑低阈值激光器提供了条件;其丰富的激发态过程为激光性能的调控提供了便利.有机材料具有良好的柔性和加工性能,可以通过自组装、3D打印、喷墨打印等多种方法制备得到高品质的光学微腔.因此,有机材料极有希望成为下一代微纳激光器的理想选择.本文从光学微腔和增益介质两方面概述了有机微纳激光器的研究进展,着重介绍了通过微腔结构和有机材料的激发态过程来调控激光性能的一系列方法,介绍了具有特定功能的复合结构有机微纳激光器的设计和构筑策略,总结了有机微纳激光在化学、生物传感和光学集成等领域的应用进展,并对其未来的发展方向和研究思路进行了展望.Micro/nanoscale lasers that can deliver intense coherent light signals at（sub）wavelength scale have attracted great interest because of their promising applications ranging from on-chip information processing to high-throughput sensing. Compared with traditional inorganic materials, organic materials are ideal platforms to construct high performance microlasers, mainly because of their superiority in flexibly assembled structures for high-quality microcavities and abundant excited-state processes with large active cross sections for high gain emissions. This review begins with an overview of the research evolution of organic microlasers in terms of microcavity resonators and energylevel gain. Then a series of strategies to tailor the microcavity structures and excited-state dynamics of organic materials for the modulation of lasing performances are highlighted. Subsequently, we present the design and construction of organic-microlaser-based hybrid structures with advanced photonic functionalities. In the following part, we introduce their applications in chemical sensing, biosensing and integrated nanophotonics. Finally, we provide our outlook on the current challenges as well as the future direction of organic microlasers. It is anticipated that this review will provide inspiration for the development of miniaturized lasers with desired performances by tailoring of excited-state processes and microcavity structures toward practical applications.
