Title | Stabilization scheme for hot-electron bolometer receivers using microwave radiation | Type | Journal Article | ||
Year | 2009 | Publication | IEEE Trans. Appl. Supercond. | Abbreviated Journal | IEEE Trans. Appl. Supercond. |
Volume | 19 | Issue | 1 | Pages | 14-19 |
Keywords | HEB, mixer, Allan variance, stabilization, radiometer equation | ||||
Abstract | We present the results of a stabilization scheme for terahertz receivers based on NbN hot-electron bolometer (HEB) mixers that uses microwave radiation with a frequency much lower than the gap frequency of NbN to compensate for mixer current fluctuations. A feedback control loop, which actively controls the power level of the injected microwave radiation, has successfully been implemented to stabilize the operating point of the HEB mixer. This allows us to increase the receiver Allan time to 10 s and also improve the temperature resolution of the receiver by about 30% in the total power mode of operation. | ||||

Title | Development of A Silicon Membrane-based Multi-pixel Hot Electron Bolometer Receiver | Type | Conference Article | ||
Year | 2017 | Publication | IEEE Trans. Appl. Supercond. | Abbreviated Journal | IEEE Trans. Appl. Supercond. |
Volume | 27 | Issue | 4 | Pages | 6 |
Keywords | Multi-pixel, HEB, silicon-on-insulator, horn array | ||||
Abstract | We report on the development of a multi-pixel Hot Electron Bolometer (HEB) receiver fabricated using silicon membrane technology. The receiver comprises a 2 × 2 array of four HEB mixers, fabricated on a single chip. The HEB mixer chip is based on a superconducting NbN thin film deposited on top of the silicon-on-insulator (SOI) substrate. The thicknesses of the device layer and handling layer of the SOI substrate are 20 μm and 300 μm respectively. The thickness of the device layer is chosen such that it corresponds to a quarter-wave in silicon at 1.35 THz. The HEB mixer is integrated with a bow-tie antenna structure, in turn designed for coupling to a circular waveguide, |

Title | New generation of nanowire NbN superconducting single-photon detector for mid-infrared | Type | Journal Article | ||
Year | 2011 | Publication | IEEE Trans. Appl. Supercond. | Abbreviated Journal | IEEE Trans. Appl. Supercond. |
Volume | 21 | Issue | 3 | Pages | 323-326 |
Keywords | SSPD | ||||
Abstract | We present a break-through approach to mid-infrared single-photon detection based on nanowire NbN superconducting single-photon detectors (SSPD). Although SSPD became a mature technology for telecom wavelengths (1.3-1.55 μm) its further expansion to mid-infrared wavelength was hampered by low sensitivity above 2 μm. We managed to overcome this limit by reducing the nanowire width to 50 nm, while retaining high superconducting properties and connecting the wires in parallel to produce a voltage response of sufficient magnitude. The new device exhibits 10 times better quantum efficiency at 3.5 μm wavelength than the “standard” SSPD. | ||||

Title | Efficiently coupling light to superconducting nanowire single-photon detectors | Type | Journal Article | ||
Year | 2009 | Publication | IEEE Trans. Appl. Supercond. | Abbreviated Journal | |
Volume | 19 | Issue | 3 | Pages | 336-340 |
Keywords | optical antennas; SNSPD | ||||
Abstract | We designed superconducting nanowire single-photon detectors (SNSPDs) integrated with silver optical antennae for free-space coupling and a dielectric waveguide for fiber coupling. According to our finite-element simulation, (1) for the free-space coupling, the absorptance of the NbN nanowire for TM-polarized photons at the wavelength of 1550 nm can be as high as 96% by adding silver optical antennae; (2) for the fiber coupling, the absorptance of the NbN nanowire for TE-like-polarized photons can reach 76% including coupling efficiency at the wavelength of 1550 nm by adding a silicon nitride waveguide and an inverse-taper coupler. | ||||

Title | Temperature dependent performances of superconducting nanowire single-photon detectors in an ultralow-temperature region | Type | Journal Article | ||
Year | 2010 | Publication | IEEE Trans. Appl. Supercond. | Abbreviated Journal | |
Volume | 21 | Issue | 3 | Pages | 336 - 339 |
Keywords | SNSPD | ||||
Abstract | We report on the performance of a fiber-coupled superconducting nanowire single-photon detector (SNSPD) from 4 K down to the ultralow temperature of 16 mK for a 1550 nm wave length. The system detection efficiency (DE) increased with de creasing the temperature and reached the considerably high value of 15% with a dark count rate less than 100 cps below 1.5 K, even without an optical cavity structure. We also observed saturation of the system DE in its bias current dependency at 16 mK, which indicates that the device DE of our SNSPD nearly reached intrinsic DE despite the device having a large active area of 20 μm × 20 μm. The dark count was finite even at 16 mK and the black body radiation becomes its dominant origin in the low temperatures for fiber-coupled devices. | ||||

Title | Suppressed critical current in superconducting nanowire single-photon detectors with high fill-factors | Type | Journal Article | ||
Year | 2009 | Publication | IEEE Trans. Appl. Supercond. | Abbreviated Journal | |
Volume | 19 | Issue | 3 | Pages | 318-322 |
Keywords | SNSPD | ||||
Abstract | In this work we present a new fabrication process that enabled the fabrication of superconducting nanowire single photon detectors SNSPD with fill-factors as high as 88% with gaps between nanowires as small as 12 nm. This fabrication process combined high-resolution electron-beam lithography with photolithography. Although this work was motivated by the potential of increased detection efficiency with higher fill-factor devices, test results showed an unexpected systematic suppression in device critical currents with increasing fill-factor. | ||||

Title | Ultrawide noise bandwidth of NbN hot-electron bolometer mixers with in situ gold contacts | Type | Journal Article | ||
Year | 2011 | Publication | IEEE Trans. Appl. Supercond. | Abbreviated Journal | |
Volume | 21 | Issue | 3 | Pages | 620-623 |
Keywords | NbN HEB mixer bandwidth | ||||
Abstract | We report a noise bandwidth of 7 GHz in the new generation of NbN hot-electron bolometer (HEB) mixers that are being developed for the space observatory Millimetron. The HEB receiver driven by a 2.5-THz local oscillator offered a noise temperature of 600 K in a 50-MHz final detection bandwidth. As the filter center frequency was swept this value remained nearly constant up to the cutoff frequency of the cryogenic amplifier at 7 GHz. We believe that such a low value of the noise temperature is due to reduced radio frequency (RF) loss at the interface between the superconducting film and the gold contacts. We have also performed gain bandwidth measurements at the superconducting transition on HEB mixers with various lengths and found them to be in excellent agreement with the results of the analytical and numerical models developed for the HEB mixer with both diffusion and phonon cooling of hot electrons. | ||||
