Single-Photon Switching: A Single Molecule Strongly Coupled to a Microcavity — •André Pscherer, Manuel Meierhofer, Daqing Wang, Hrishikesh Kelkar, Diego Martín-Cano, Stephan Götzinger, and Vahid Sandoghdar — Max-Planck-Institut für die Physik des Lichts, Erlangen, Germany

Nonlinear light-matter interactions usually involve macroscopic materials and high intensities, often involving pulsed lasers. Considering the intrinsic optical nonlinearity of atoms and molecules, however, one can imagine performing operations such as switching by using single quantum emitters and single photons. We show that single organic molecules embedded in a solid nanoscopic matrix can indeed provide access to this realm when coupled to a Fabry-Pérot cavity with a very small mode volume. We demonstrate vacuum Rabi oscillations, single-photon switching and four-wave mixing at the level of single photons in the strong coupling regime [1].
