FIG. 1.

PL spectrum from the ensemble of QDs. Excitation wavelength is . The thick upward arrow indicates the energy of the continuous-wave laser used for single dot spectroscopy.

FIG. 2.

PL spectra from different mesa sizes (a)–(c) and from the area where QDs were completely removed (d).

Image of FIG. 3.
FIG. 3.

PL spectra at excitation powers of , , and . The circles show experimental data, and the solid lines show fitting results using a Lorenzian function. At the excitation power of , we took account of two additional peaks for fitting. (Fitting curves are not shown.) One peak is below the energy of (Gaussian function) and the other one is at the higher-energy side of XX (Lorenzian function).

FIG. 4.

Integrated intensity as a function of excitation power on logarithmic scales. The integrated intensities were obtained by fitting the spectrum to Lorenzian function. The lines show the slopes of individual peaks.
