InGaAsN triple-quantum-well (TQW) 4-μm ridge waveguide (RWG) lasers were fabricated using pulsed anodic oxidation. High output power of 290 mW (both facets), low transparency current density of 389 A/cm2 (equivalent to 130 A/cm2/well) and high characteristic temperature (T0) of 157.2 K were obta...
