Abstract :
Summary form only given. We report on the cw performance of optimized facet-coated InGaAs/InGaAsP/InGaP (/spl lambda/=0.95 /spl mu/m) diode lasers as well as on the improvement in their performance as the facets are passivated by in-situ growth of ZnSe half-wave films. The results represent record-high values for both front-facet-emitted cw power: 2.9 W, as well as maximum cw wallplug efficiency: 54%.
