Input–output characteristics of QD-micropillar emitters for (a) LEDs, (b) cavity-enhanced LED and (c) lasers. The data points are from experiment and the gray curves are from theory. The left ordinate is the average detector counts over the integration period, and the right ordinate is the calculated average intracavity photon number n_p in the lasing mode. The dashed lines indicate the nominal lasing determined by n_p=1. The red numbers and lines indicate power law exponents and curves, respectively, as described in the main paper.
