The minimalistic design of InGaN-based MQW microdisk lasers based on whispering gallery mode (WGM) resonances has been attracting research interests in recent years. To compete with the prevalent InGaN-based VCSELs and edge-emitters, microdisk lasers must demonstrate superior performance under electrical injection. Yet, the challenges in the shift from initial optically pumped investigations to studies centered on electrically injected microdisk lasers has posed a barrier to successful commercialization.
