Photon Statistics Excitation Spectroscopy of a Single Two Level System — •Janik Wolters1,2, Max Strauss2, Marlon Placke2, Sören Kreinberg2, Christian Schneider3, Martin Kamp3, Sven Höfling3, and Stephan Reitzenstein21Universität Basel, Departement Physik, CH-4056 Basel — 2Institut für Festkörperphysik, Quantum Devices Group, Technische Universität Berlin, Hardenbergstrasse 36, EW 5-3, 10623 Berlin, Germany — 3Technische Physik, Universität Würzburg, Am Hubland, 97074 Würzburg, Germany

The interaction of coherent light with a single two level system (TLS) is one of the corner stones of quantum optics. In recent years experiments in this exciting field of quantum optics have been extended from atomic systems to semiconductor nanostructures, e.g. to the coherent control of self-assembled quantum dots (QDs). Here, we address the so far unexplored regime of resonance fluorescence in which the QD is excited not with a coherent laser, but with a narrowband chaotic light source. By analysing the resonantly scattered emission of the TLS, we find that the photon statistics of the excitation source greatly influences the TLS's dynamics in quantitative agreement with theoretical predictions.
