Abstract
A technique has been developed for improving the quantum efficiency and the temperature stability of ridge waveguide AlGaAs/GaAs quantum well lasers. Excellent lasing characteristics, including a differential quantum efficiency of 75%, have been achieved in graded-index waveguide separate-confinement heterostructure single quantum well lasers fabricated by this technique.Keywords
