Figure 4

Spectral linewidth versus pump power of QD-micropillar emitters for (a) LEDs, (b) cavity-enhanced LED and (c) lasers. The gray curves are from theory, and the data points are from experiment. Filled symbols indicate the scanning Fabry–Pérot interferometer or spectrometer results, and open symbols indicate the results from the analysis of measurements.
