We report on the growth and fabrication of (InGa)As quantum dot classical and quantum light emitters, i.e. edge-emitting laser diodes and single photon sources, respectively. With an InAlAs/InGaAs composite overgrown layer, InAs quantum dots exhibit high optical quality and large state-separation that are desirable for laser diodes with high characteristic temperature. Single photon source has been realized by optical pumping a single quantum dot through a submicron aperture fabricated on a low-density self-assembled InGaAs quantum dots ensemble.
