Abstract

Ridge waveguide quantum well (QW) diode lasers in the green/blue region have been operated at voltages as low as 7 V in ZnCdSe/ZnSSe/ZnMgSSe pseudomorphic separate confinement heterostructures. These lasers include a p-Zn(Se, Te) graded gap ohmic contact layer to the top metal electrode. Without any attempt at heatsinking, and without reflective facet coatings, these devices have operated at pulsed duty cycles of 20% at room temperature, with average power output of several milliwatts.
