Figure 5From: A low-noise single-photon detector for long-distance free-space quantum communicationLong-time afterpulsing analysis. (a) Analysis scheme that considers all events within the window length l. (b) Resulting histogram with an exponentially increasing bin size. This histogram uses the same data as Fig. 4 (114109 counts, C30902SH APD at −100∘C and 14 V overvoltage) but visualises the entire afterpulse characteristic at onceBack to article page
