On-wafer continuous-wave operation of InGaN/GaNviolet laser diodes

Abstract
Continuous-wave operation of etched-facet InGaN/GaN multi-quantum-well ridge-waveguide laser diodes grown by low pressure MOVPE on sapphire substrate has been achieved on-wafer for > 2 min at 15% above threshold. The threshold current density and voltage were 9.1 kA/cm2 and 7.6 V, respectively, at 15°C, and the lasing wavelength was 400.6 nm.
