1.5 µm laser on GaAs with GaInNAsSb quinary quantum well

Abstract
A 1.50 µm broad area edge emitting laser is demonstrated with a structure grown by molecular beam epitaxy on a GaAs substrate. The active region is based on a single GaInNAsSb quantum well. The threshold current density is 3.5 kA/cm2. Output power over 22 mW per facet is achieved.
