Abstract
- Microdisk lasers feature low-loss, high-quality whispering gallery modes that offer the potential for ultralow-threshold lasing that is not limited by challenges in mirror fabrication. Here we report fabrication and optical measurements of GaN-based microdisk lasers with a very low threshold of 300 W cm<superscript>−2</superscript>—orders of magnitude lower than any previous GaN microdisk laser. This is also the first report of room-temperature, continuous-wave (CW) lasing in a GaN microdisk. [ABSTRACT FROM AUTHOR]
