  • Abstract
    The authors report the lowest threshold current density to date of a strained InGaAs/GaAs/AlGaAs single quantum well separate confinement heterostructure laser grown on a (111)B GaAs substrate. A Jth value as low as 87 A/cm2 has been obtained for a 2500 μm long broad area laser. The internal quantum efficiency is estimated to be 82% and the internal loss is 5.5 cm-1
