高质量的纳米线可以来回传播光，并作为法布里-珀罗（FP）谐振器，以提高光放大的光学增益。[ 4-6 ]这种纳米线腔的主要缺点是它们在端面处的低反射率，[ 7 ]这意味着大多数行进的光子从线尖端处的腔中耦合输出。一个简单而有效的解决方案是将纳米线的两端连接成伪环构象，[8，9]其中光可以通过形成回音壁模式（WGM）共振而更好地配置。[ 10 ]这些人造光学几何形状的实际应用仍然受到阻碍，因为它们不方便制造，并且在接合点处存在意想不到的光散射和能量泄漏。有机材料的化学多功能性和柔韧性允许多种微/纳米组装，[ 11-13 ]
High quality nanowires can travel light forth and back, and serve as Fabry-Pérot (FP) resonators to enhance optical gains for light amplifi cation. [ 4–6 ] The major drawback of such nanowire cavities is their low refl ectivity at end facets, [ 7 ] which implies most of traveled photons are outcoupled from cavities at wire tips. One simple yet effective solution is to join the two ends of a nanowire into a pseudo-ring conformation, [ 8,9 ] where the light might be better confi ned via the formation of whispering gallery mode (WGM) resonance. [ 10 ] Practical applications of these artifi cial optical geometries are still hindered for their inconvenient fabrication and the unexpected light scattering and energy leakage at joint points. The chemical versatility and fl exible nature of organic materials allow for numerous kinds of micro/nano-assemblies, [ 11–13 ]
