Abstract
Ridge waveguide quantum well (QW) diode lasers in the green/blue region have been operated at voltages as low as 7V in ZnCdSe-ZnSSe-ZnMgSSe pseudomorphic 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.
