Abstract

We directly measure the optical gain and threshold current of lithographically-defined quantum dots. A peak groundstate gain of 1.8 cm-1 is determined. We also measure the recovery dynamics of the groundstate with the device biased above and below transparency using ultrafast differential transmission spectroscopy.
