Photon antibunching from a single lithographically defined InGaAs/GaAs quantum dot

Opt Express. 2011 Feb 28;19(5):4182-7. doi: 10.1364/OE.19.004182.

Abstract

We demonstrate photon antibunching from a single lithographically defined quantum dot fabricated by electron beam lithography, wet chemical etching, and overgrowth of the barrier layers by metalorganic chemical vapor deposition. Measurement of the second-order autocorrelation function indicates g(2)(0)=0.395±0.030, below the 0.5 limit necessary for classification as a single photon source.
