Fig. 4
Telecom-band device results. a Normalized histogram of photon counts versus time difference Δt measured for photons with different wavelength from 1480 to 1640 nm. b Normalized histogram measured for a mixture of two coherent light sources with their wavelengths separated by 2.5 nm. The red dashed line represents double-Gaussian fitting for the measured data, which is the sum of two Gaussian distribution displayed in blue dashed lines. c Normalized histogram measured for a single-color source with slightly varied wavelength step by 0.1 nm. d Normalized histogram measured for a 1560 nm pulsed source as a function of the arrival time difference between the averaged detector signal (t1 + t2)/2 and laser synchronization signal t0. All the histogram results are measured with the nanowire detector biased at 80% of ISW. All the results are taken from Device A (see Supplementary Note 1)
