Abstract

We use the third- and fourth-order autocorrelation functions and to detect the non-classical character of the light transmitted through a photonic-crystal nanocavity containing a strongly-coupled quantum dot probed with a train of coherent light pulses. We contrast the value of with the conventionally used and demonstrate that in addition to being necessary for detecting two-photon states emitted by a low-intensity source, provides a more clear indication of the non-classical character of a light source. We also present preliminary data that demonstrates bunching in the fourth-order autocorrelation function as the first step toward detecting three-photon states.
