(Nanowerk News) Dielectric optical microresonators confine and concentrate light in a tiny circular path due to multiple near total internal reflections at the curved dielectric-air interface, where ...
Figure 1. Schematic of a tunable microlaser based on phase-change perovskite gain medium, sandwiched between Au mirror and DBR reflector sitting on a quartz glass substrate, pumped by blue-violet ...
Colloidal quantum-dots (CQDs) have emerged as promising gain media for lasers, offering low lasing thresholds, compatibility with low-cost solution-based synthesis and processing methods, and tunable ...
