We have characterized self-assembled InAs quantum dots grown on the top of a single InGaAs/GaAs quantum well (QD's:QW) by measuring photoluminescence (PL) spectra as an effective technique. We have found that the linewidths of the PL peaks for the QD's:QW are narrower than that for the InAs quantum
