Abstract
A 1 W continuous-wave laser operation via the ground state of vertical ly coupled InGaAs quantum dots (VCQDs) in an AlGaAs matrix is demonstr ated. VCQDs are directly revealed in transmission electron microscopy images of the laser structure. Ninety-six percent internal quantum eff iciency is realized. The laser gain maximum shifts significantly with drive current towards higher photon energies in agreement with the rel atively broad size distribution of VCQDs.
