Low-frequency phase locking in high-inductance superconducting nanowires

Robert H. Hadfield, Aaron Miller, Sae Woo Nam +2 more

Niobium nitride nanowires show considerable promise as high-speed single-photon detectors. We report the observation of an anomalous low-frequency (∼10MHz) response in long, superconducting NbN nanowires (100nm wide, 4nm thick, and 500μm long). This behavior, although strikingly reminiscent of the ac Josephson effect, can be explained by a relaxation oscillation resulting from the high kinetic inductance of the type II nanowire. We simulate all of the observed effects using a simple resistive-hotspot/series-inductor model. The voltage pulses observed are indistinguishable from the pulses induced by visible photons, and our observations suggest noise-induced relaxation oscillations are one mechanism for the dark counts in photon detectors.

Characterize the Speed of a Photon-Number-Resolving Superconducting Nanowire Detector

Tao Xu, Hao Hao, Xiang Li +8 more

Superconducting series nanowire single-photon detectors (SNDs) have been used for resolving photon numbers. But it can also exhibit a higher counting rate than a single superconducting nanowire single-photon detector (SNSPD), because the serial architecture allows multiple detectors working in parallel and the inductance of each pixel is reduced. In this paper, we found each pixel of the SND could reset fast although the whole detector took a much longer time for recovering. Therefore, the speed of an SND with a large kinetic inductance of 1.25 μH was characterized and compared to a standard SNSPD with the same total inductance. By measuring the detected photon rate over the input photon rate, we obtained a photon counting rate enhancement by 7.5 times. Meanwhile, the timing jitter of the SND was 63 ps at single photon detection regime. Our results show that the series structure and the readout scheme are quite practical in realizing high speed single-photon detectors besides resolving photon numbers.

High-efficiency fast superconducting nanowire single-photon detector with a reflection grating structure

Miṅ Gu, Xiaolin Lin, Dongmei Liu +2 more

Superconducting nanowire single-photon detectors (SNSPDs) with a reflection grating structure are designed to enhance system detection efficiency and detection rate. The absorption capacity of the superconducting nanowires reached 92% at wavelengths of 1550 nm. It reduced the total filling factor of superconducting nanowires to only 0.25, decreased the kinetic inductance of SNSPDs, and improved the count rates.
