Coupling of quantum emitters and metallic nanoantennae for the generation of nonclassical light at high rates

We investigate the optical properties of a hybrid system consisting of a quantum emitter that is strongly coupled to a pair of metallic nanoparticles. Emphasis is put on the exploitation of such a hybrid system as a highly efficient source for nonclassical light. The properties of the emitted light are analyzed in detail for a system that was designed to maximize the single-photon emission rates. Such sources may represent important constituents for the future architecture of fully integrated quantum circuits and may soon drastically improve the performance of quantum information protocols.
