All-optical control of photon statistics with a single atom in an optical cavity — •Haytham Chibani, Christoph Hamsen, Tatjana Wilk, and Gerhard Rempe — Max-Planck-Institute of Quantum Optics, Hans-Kopfermann-Str. 1, 85748 Garching, Germany

The realization of controllable nonlinearities at the level of single quanta of matter and light is one of the main goals of quantum optics. Here, we show that non-classical states of light can be generated and optically controlled in an atom-cavity system via the fruitful combination of cavity quantum electrodynamics (QED) in the strong coupling regime with cavity electromagnetically induced transparency (EIT) as predicted by a recent theoretical study [1]. We report on a controlled transition from sub- to super-Poisson photon statistics in the light transmitted through a cavity containing a single atom. Moreover, we present transmission spectra showing for the first time both the EIT effect and the normal mode structure which is the signature of a strongly coupled cavity QED system.
