WebA quantum dot single-photon source is based on a single quantum dot placed in an optical cavity. It is an on-demand single-photon source. ... Single photon sources exhibit antibunching. As photons are emitted one at a time, the probability of seeing two photons at the same time for an ideal source is 0. WebIt is shown by example that sub-Poissonian photon-counting statistics need not imply photon antibunching, but can be accompanied by photon bunching, i.e., by the tendency of two photons to be close together more frequently than further apart. Some comments on the relation between antibunching and sub-Poissonian statistics are made.
