Paper Abstract

High power highly-efficient AlGa(In)As/GaAs multimode diodes operating at 915 nm range have been developed. 2 mm long-cavity Chips-On-Submount demonstrate 72% peak power conversion efficiency at 25°C heatsink temperature. Peak power efficiency over 50% was recorded up to 130°C heatsink temperature. CW power launched at 7°C heatsink temperature from 20 um wide aperture devices is around 8.5 W and is thermally limited. This output power level translates into record-high brightness on the facet: > 65 MW/cm2. Device reliability assessment indicates high potential of such devices to operate reliably at high electrical and optical power densities.
