Figure 2: Resonant fluorescence measurement used to monitor the exciton population.

(a) Sketch of the experimental setup: the laser polarization is controlled by a polarizing beam splitter and a half waveplate. The reflectivity is measured by collecting the signal at exit 1 while the resonant fluorescence is measured at exit 2 in crossed polarization. (b) Schematic representation of the theoretical model used to describe the experiment. See text for details. (c) Resonant fluorescence intensity (log. scale) measured in crossed polarization as a function of energy and applied bias. The laser is resonant to the V mode energy. (d,e) Time dependence of the 56 ps excitation pulse (blue) and the collected emission in H polarization (red). d, experiment; e, calculations.
