Performance Improvement of GaN-Based Vertical-Cavity Surface-Emitting Lasers by Using Tapered SiO₂-Buried Structure

IEEE Photonics Journal
In GaN-based vertical-cavity surface-emitting lasers (VCSELs) with insulator-buried structure, the strong index guiding will introduce higher order modes. In this paper, we present a novel GaN-based VCSEL with a tapered SiO2-buried structure by numerical
