Paper Abstract

We report results for broad area edge emitting lasers having AlInGaAs active regions that exhibit low thresholds, high T0 and T1 and high efficiencies. The lasers were grown on InP substrates using MOCVD. This paper analyzes the effects of doping, epilayer design, wavelength dependence and number of QWs on device performance. Our results show that the concentration and offset of zinc doping in the p-cladding layer plays a major role in carrier confinement and hence high temperature performance. The difference in surface mobility of Al adatoms (as compared to In or Ga) poses some challenges in the growth of AlInGaAs.
