Optically pumped InxGa 1-xN / InyGa 1-yN multiple quantum well vertical cavity surface emitting laser operating at room temperature

Abstract

x N/In y Ga 1-y N multiple quantum well without Bragg mirrors under photo-excitation. At high excitation intensity, one of the modes of the Fabry-Perot cavity formed by the GaN/sapphire and the GaN/air interfaces, shows a strong superlinear increase in intensity with excitation intensity rise. The vertical cavity surface emitting laser (VCSELs) structure is… (More)
