Whispering-gallery-mode (WGM) resonators of semiconductor microdisks have been applied for achieving low-threshold and narrow-linewidth microlasers, but require sophisticated top-down processing technology. Organic single-crystalline hexagonal microdisks (HMDs) of p-distyrylbenzene (DSB) self-assembled from solution can function as WGM microresonators with a cavity quality factor (Q) of 210. Both multiple- and single-mode lasing had been achieved using DSB HMDs with an edge length of 4.3 and 1.2 μm, respectively. These organic microdisks fabricated by bottom-up self-assembly approach may offer potential applications as low-threshold microlaser sources for photonic circuit integration.
whispering-gallery-mode (WGM) 半导体微盘谐振器已被应用于实现低阈值和窄线宽微激光器，但需要复杂的自上而下的加工技术。由溶液自组装的 p-二苯乙烯（DSB）有机单晶六方微盘（HMD）可用作 WGM 微谐振器，其腔品质因数（Q）为 210。使用边长分别为 4.3 和 1.2 μm 的 DSB HMD，分别实现了多模和单模激光。通过自下而上的自组装方法制造的这些有机微盘可能作为光子电路集成的低阈值微激光源具有潜在的应用。
