Figure 4: Dependence of the detector output on the photon flux.

(a) Detected flux dependence of the distribution of output voltage pulses from an electric field-modulated Si-APD. Red corresponds to high intensity and blue to low intensity. (b) Measured occurrence probabilities of the N=0–4 photon peaks (symbols), plotted as a function of μ′, and the fit obtained using a Poissonian distribution to describe the statistics of the source (lines) for a photon detection efficiency of η=7.4%.
