Abstract
A 1 W continuous-wave laser operation via the ground state of vertically coupled InGaAs quantum dots (VCQDs) in an AlGaAs matrix is demonstrated. VCQDs are directly revealed in transmission electron microscopy images of the laser structure. Ninety-six percent internal quantum efficiency is realized. The laser gain maximum shifts significantly with drive current towards higher photon energies in agreement with the relatively broad size distribution of VCQDs.This publication has 5 references indexed in Scilit:
