Single-mode ultraviolet whispering gallery mode lasing from a floating GaN microdisk

Gangyi Zhu, Jiyuan Guo, Chunxiang Xu, Jiaping Li, Jun Dai, Yongjin Wang, Jitao Li
We fabricated a floating GaN microdisk supported by a silicon pillar through photolithography, dry-etching GaN, and isotropic wet-etching silicon methods. Single-mode ultraviolet whispering gallery mode (WGM) lasing was obtained from the floating GaN microdisk under optical pumping conditions at ...
