An organic molecule strongly coupled to a microcavity: Single-photon nonlinearity — •André Pscherer1, Manuel Meierhofer1, Daqing Wang1, Hrishikesh Kelkar1, Diego Martín-Cano1, Tobias Utikal1, Stephan Götzinger2,1,3, and Vahid Sandoghdar1,2 — 1Max Planck Institute for the Science of Light, Erlangen, Germany — 2Department of Physics, Friedrich-Alexander University Erlangen-Nürnberg (FAU), Erlangen, Germany — 3Graduate School in Advanced Optical Technologies (SAOT), Friedrich-Alexander University Erlangen-Nürnberg, Erlangen, Germany
The response of a single quantum emitter to a single photon is qualitatively different from its response to classical light. In a free-space scheme, optical nonlinearities are intrinsically weak. Here, we show that by reaching the strong coupling regime of cavity quantum electrodynamics, four-wave mixing and optical switching become possible at the level of single photons and single molecules. Furthermore, we demonstrate vacuum Rabi oscillations and super bunching [1].
