Title | Potential of a superconducting photon counter for heterodyne detection at the telecommunication wavelength | Type | Journal Article | ||
Year | 2016 | Publication | Opt. Express | Abbreviated Journal | Opt. Express |

Abstract | Here, we report on the successful operation of a NbN thin film superconducting nanowire single-photon detector (SNSPD) in a coherent mode (as a mixer) at the telecommunication wavelength of 1550 nm. Providing the local oscillator power of the order of a few picowatts, we were practically able to reach the quantum noise limited sensitivity. The intermediate frequency gain bandwidth (also referred to as response or conversion bandwidth) was limited by the spectral band of a single-photon response pulse of the detector, which is proportional to the detector size. We observed a gain bandwidth of 65 MHz and 140 MHz for 7 x 7 microm2 and 3 x 3 microm2 devices, respectively. A tiny amount of the required local oscillator power and wide gain and noise bandwidths, along with unnecessary low noise amplification, make this technology prominent for various applications, with the possibility for future development of a photon counting heterodyne-born large-scale array. | ||||

Title | Sensitivity of a superconducting nanowire detector for single ions at low energy | Type | Journal Article | ||
Year | 2012 | Publication | Nanotechnol. | Abbreviated Journal | Nanotechnol. |
Volume | 23 | Issue | 6 | Pages | 065501 (1 to 5) |
Keywords | NbN SSPD, SNSPD, superconducting single ion detector, SSID, SNSID | ||||
Abstract | We report on the characterization of a superconducting nanowire detector for ions at low kinetic energies. We measure the absolute single-particle detection efficiency eta and trace its increase with energy up to eta = 100%. We discuss the influence of noble gas adsorbates on the cryogenic surface and analyze their relevance for the detection of slow massive particles. We apply a recent model for the hot-spot formation to the incidence of atomic ions at energies between 0.2 and 1 keV. We suggest how the differences observed for photons and atoms or molecules can be related to the surface condition of the detector and we propose that the restoration of proper surface conditions may open a new avenue for SSPD-based optical spectroscopy on molecules and nanoparticles. | ||||

Title | NbN superconducting single-photon detector coupled with a communication fiber | Type | Journal Article | ||
Year | 2005 | Publication | Elektronika : konstrukcje, technologie, zastosowania | Abbreviated Journal | |
Volume | 46 | Issue | 6 | Pages | 51-52 |
Keywords | NbN SSPD, SNSPD | ||||
Abstract | We present novel superconducting single-photon detectors (SSPDs), based on ultrathin NbN films, designed for fiber-based quantum communications (lambda = 1.3 žm and 1.55 žm). For fiber-based operation, our SSPDs contain a special micromechanical construction integrated with the NbN structure, which enables efficient and mechanically very stabile fiber coupling. The detectors combine GHz counting rate, high quantum efficiency and very low level of dark counts. At 1.3 – 1.55 žm wavelength range our detector exhibits a quantum efficiency up to 10%. | ||||

Title | Сверхпроводящий однофотонный детектор на основе ультратонкой пленки NbN | Type | Journal Article | ||
Year | 2005 | Publication | Квантовая электроника | Abbreviated Journal | |
Volume | 35 | Issue | 8 | Pages | 698-700 |

Abstract | Представлены результаты исследований сверхпроводящих однофотонных детекторов, изготовленных из ультратонкой пленки NbN. Развитие технологического процесса изготовления детекторов, а также снижение рабочей температуры до 2 К позволили существенно увеличить квантовую эффективность: для видимого света (λ = 0.56 мкм) она составила 30%–40%, т.е. достигла предела, определяемого коэффициентом поглощения пленки. С ростом длины волны квантовая эффективность экспоненциально падает, составляя ~20% на λ=1.55 мкм и ~0.02% на λ = 5 мкм. При скорости темнового счета ~10-4s-1 экспериментально измеренная эквивалентная мощность шума составила 1.5 × 10-20 Вт/Гц-1/2; в дальнейшем она может быть уменьшена до рекордно низкого значения 5 × 10-21 Вт/Гц-1/2. Временное разрешение детектора равно 30 пс. | ||||
