Cavity quantum dynamics with pumped few-level emitters

Abstract

Cavity quantum electrodynamics attracted a lot of attention due to possible applications in various areas. Here we demonstrate increased photon-photon correlations in a setup consisting of a moderately pumped two-level emitter embedded in an optical microresonator. The effect occurs beyond the secular approximation. Furthermore, in a slightly modified scheme, the cavity field can be conveniently modified using quantum interference effects.
