Reduction of the lasing threshold in optically pumped AlGaN/GaN lasers with two-step etched facets
Sergi Cuesta, Lou Denaix, Florian Castioni +2
We report a two-step process to obtain smooth and vertical {10-10} m-plane facets in AlGaN/GaN separate confinement heterostructures designed to fabricate UV lasers emitting at 355…
