We propose a general approach for obtaining dual-wavelength organic microlasers in amphiphilic Janus resonators, where hydrophilic and hydrophobic dyes can be spatially separated via polarity-driven encapsulation. Low-threshold dual-wavelength lasing was achieved in a single Janus particle with well-modulated output. This universal approach enables flexibly designing the lasing wavelength of the Janus microlasers in the full visible spectrum by systematically altering the encapsulated laser dyes. Our findings demonstrate a promising route to the photonic integration at the micro-/nanoscale that may lead to the innovation of concepts and device architectures for multifunctional optoelectronic applications.
我们提出了一种在两亲性Janus谐振器中获得双波长有机微激光器的通用方法，其中亲水性和疏水性染料可通过极性驱动封装在空间上分离。在单个Janus粒子中实现了低阈值双波长激光发射，其输出得到了良好调制。这种通用方法能够通过系统地改变封装的激光染料，在整个可见光谱范围内灵活设计Janus微激光器的激光波长。我们的研究结果展示了一条通往微/纳米尺度光子集成的有前景的途径，这可能会引发多功能光电子应用的概念和器件架构的创新。
