Microlasers
A self‐assembled CdSe/CdS@Cd1‐xZnxS core/buffer‐shell@graded‐shell nanoplatelets whispering‐gallery‐mode microlaser with ultralow lasing threshold, high quality factor, and stable single‐frequency operation is proposed by Jun Yang, Van Duong Ta, Handong Sun in article number 2108884. The results highlight the significance of interface engineering on the optimization of gain properties...
The realization of efficient on‐chip microlasers with scalable fabrication, ultralow threshold, and stable single‐frequency operation is always desired for a wide range of miniaturized photonic systems. Herein, an effective way to fabricate nanostructures‐ whispering‐gallery‐mode (WGM) lasers by drop‐casting CdSe/CdS@Cd1−xZnxS core/buffer‐shell@graded‐shell nanoplatelets (NPLs) dispersion onto silica...
