Paper Abstract

The OMVPE growth and performance of graded-index separate-confinement heterostructure strained quantum-well InGaAs-AlGaAs diode lasers are reviewed. Broad-stripe lasers have exhibited Jth as low as 60 A cm-2 for a cavity length L equals 1500 micrometers and differential quantum efficiency (eta) d as high as 90% for L equals 300 micrometers . Similar heterostructures have been used to fabricate traveling wave amplifiers with a laterally tapered gain region that emit over 1 W cw in a nearly diffraction-limited spatial lobe at 0.98 micrometers , linear arrays of 200-micrometers -long uncoated ridge-waveguide lasers with average threshold currents of 4 mA and (eta) d approximately 90%, and high-power broad-stripe lasers with power conversion efficiency exceeding 50% at 75 degree(s)C.
