The kink-free output power in 980-nm emitting laser diodes can be increased by 30%-50% in ridge-waveguide devices when the thickness of the oxide is decreased such that the optical field is allowed to ...

We present a novel approach to flattening the in-chip thermal profile that develops within multiple-emitter, 1-cm-wide bars by optimally manipulating heating at the edge-emitters. The best-designed ...
