From: A study to develop a robust method for measuring the detection efficiency of free-running InGaAs/InP single-photon detectors

Figure 7

Detection efficiency of the InGaAs/InP SPAD detector measured by all participants between the mean photon number per pulse from 0.01 and 2.4, which correspond to a photon rate of approximately 1100 photon/s and 193,000 photon/s for a wavelength of 1550 nm, respectively. The data in red are referred to raw data; i.e. without correcting the SPAD dead time, and the green are the corrected data according to equation (4). Error bars: expanded uncertainty (\(k=2\))
