WebMar 11, 2004 · Shown in Fig. 1 are dark count rates as a function of the reduced bias current I/I c for two different temperatures. Data taken at the lower temperature of T=1.8 K =0.41T c (squares in Fig. 1) follow the simple model according to Eq. (1) and a squared current dependence. The dotted line is the result of a least-squares fit. Not only is the … Webrate significantly, the dark count rate is still thousands of counts per second. The wavelengths of the noise photons are spectrally broadend and flat and are evenly distributed around the narrow signal spectrum at 710 nm. Therefore, a narrow filter can help to further reduce the dark count rate. We use a holographic band-pass filter after the
