内容記述 |
Suppressing the dark count rate (DCR) is one of the main issues in the development of the superconducting nanowire single-photon detector (SNSPD). Here we study the effect of suppressing DCR using the various optical bandpass filters cooled at 3 K. The DCR, which is dominated by the background blackbody radiation at room temperature through an optical fiber, can be strongly suppressed by introducing the cold filter. Using the bulk commercial filter with the bandwidth of 10 nm and the high transmission above 85 %, the DCR is improved about 29 dB with 2.4 dB decreasing of the system detection efficiency (η). The noise equivalent power (NEP) reaches 1.5 × 10-18 and the figure of merit (FOM) reaches 1.8 × 109. These values are compared to the results using other type of filters. |
