Surface-Mode Lasing from Optically Pumped InGaN/GaN Heterostructures

Abstract

We have demonstrated vertical lasing without Bragg reflectors in structure with multiple InGaN/GaN insertions. Laser action is confirmed by superlinear dependence of the output intensity versus excitation density and by appearance of a single lasing mode defined by a vertical Fabry-Perrot cavity formed by GaN/air and GaN/Al2O3 interfaces. Effect of interaction of gain spectrum and cavity modes is demonstrated.
