Abstract

The invention provides a superconducting nanowire single-photon detection system with a tapered transmission line. The superconducting nanowire single-photon detection system comprises a superconducting nanowire single-photon detector, the tapered transmission line, a high-pass filter, a three-port device, a current source and an amplifier; one end of the tapered transmission line is connected with the superconducting nanowire single-photon detector; one end of the high-pass filter is connected with the end, connected to the superconducting nanowire single-photon detector, of the tapered transmission line, and the other end of the high-pass filter is grounded; a first port of the three-port device is connected with the end, away from the superconducting nanowire single-photon detector andthe high-pass filter, of the tapered transmission line; one end of the current source is connected with a second port of the three-port device; the input end of the amplifier is connected with a thirdport of the three-port device, and a ground terminal of the amplifier is grounded; and the superconducting nanowire single-photon detector, the tapered transmission line and the high-pass filter areintegrated on the same chip. The overall properties, such as amplification of high-frequency signals, lowering of time jitter and increasing of the counting rate, of the superconducting nanowire single-photon detector can be achieved.

Description

technical field [0001] The invention belongs to the technical field of light detection, in particular to a superconducting nanowire single-photon detection system with a graded transmission line. Background technique [0002] Superconducting nanowire single photon detector (SNSPD) is a new type of single photon detection technology developed in the past ten years. Its biggest advantage over semiconductor detectors is its ultra-high detection efficiency and fast response. speed, negligible dark counts, and extremely low timing jitter with a spectral response spanning visible to infrared. In 2001, the Gol'tsman group of Moscow Normal University first prepared a 200nm-wide superconducting nanowire by using a 5nm-thick NbN ultra-thin film, successfully realized single-photon detection from visible light to near-infrared, and opened the single-photon detection of superconducting nanowires. The first of its kind in photon detectors. Since then, many countries and research groups...
