Identifying spectral jumps through the photon statistics.
(a) Intensity histogram for the X1− transition of QD D (s = 0.8, δaverage = 70 MHz, ΔDiffusion = 70 MHz). Applying full counting statistics reveals a bimodal detuning probability distribution. The data is shown as blue stepped curve; the red curve with red shading shows a fit to the dominant of the distribution modes. Bottom, the residual (data as blue diamonds) reveals the second weaker mode. (b) Sketch of the physical process. The QD resonance switches discontinuously between two frequencies. Relative frequency denotes the detuning between laser and the QD resonance in the dominant distribution mode. The fit from (a) puts the probability to be in the brighter (darker) mode to ~0.965 (0.035).
