Abstract

We describe the fabrication and optical properties of a 3λ/2 InGaN/GaN-based microcavity using "upper" and "lower" silica/zirconia mirrors. The fabrication of this structure involved selective removal of an AlInN layer following multistep thinning of a free-standing GaN substrate. Photoluminescence spectra show a narrowing of the excitonic emission from InGaN/GaN quantum wells in the microcavity, giving a cavity quality factor Q exceeding 400.
