Fabrication of GaN-based micro-cavity light emitters

GaN based microcavity light emitters are featured with small compact footprint, high quality (Q) factors, small mode volumes, and low power consumption. They are therefore attracting much attention in various fields, including photonics, visible light communications, quantum information, and cavity quantum electrodynamics (CQED). In this paper, we will introduce our recent progress in GaN-based micro-cavity light emitters including resonate cavity LEDs (RCLEDs) and vertical cavity surface emitting lasers (VCSELs).
