Influence of spectral diffusion on resonant photon counting statistics.
(a) The QD optical transition frequency shifts as a consequence of local electric field noise such that a laser of fixed frequency drives the transition with a time-dependent detuning. Here we show the absorption lineshape at three instances in time. Right panel: intensity histograms corresponding to the three detunings depicted on the left (same colour code). The cumulative histogram (grey shaded) strongly deviates from the ideal Poissonian distribution. (b) Calculation of full counting statistics histograms for a Gaussian diffusion distribution with a full-width-half-maximum ΔDiffusion equal to the natural linewidth of 250 MHz. The excitation detuning δaverage denotes the average detuning of the laser from the QD resonance. The saturation parameter is s = 1, the average count rate on resonance a would correspond to 100 counts per bin in the absence of environment effects. Right panel: Linecuts from the calculation for three detunings.
