Dual‐color lasing generated and outcoupled controllably at microscale is crucial for the realization of highly integrated photonic devices. This work constructs a type of organic microdisk/microwire dual‐color laser heterostructures via a step‐by‐step directed molecular assembly strategy based on hydrogen‐bond‐assisted facet‐selective growth mechanism. The microdisk therein can act as high‐quality whispering‐gallery‐mode microcavity for blue lasing, while the interconnected wire functions as the Fabry–Pérot resonator to deliver green lasing. Moreover, the blue/green dual‐color lasing is simultaneously generated and controllably outcoupled from the tip of the wire, which provides a proof‐of‐concept trial for the flexible integration of microlasers with different wavelengths toward multiband photonic circuits.

用于双色激光输出耦合的有机复合材料微盘/微丝异质结构的受控组装

在微尺度上可控地生成和输出双色激光对于实现高度集成的光子器件至关重要。这项工作通过基于氢键辅助小平面选择性生长机制的分步定向分子组装策略，构建了一种有机微盘/微线双色激光异质结构。其中的微盘可以充当蓝色激光的高质量耳语-画廊模式微腔，而互连的导线则充当法布里-佩罗特共振器以传递绿色激光。此外，蓝/绿双色激光同时生成并从导线尖端可控地分离，这为将具有不同波长的微激光灵活地集成到多波段光子电路中提供了概念验证试验。
