  Title On-Chip Single Plasmon Detection Type Journal Article
  Year (down) 2010 Publication Nano Letters Abbreviated Journal Nano Lett.  
  Volume 10 Issue Pages 661-664  
  Keywords optical antennas; SSPD; Single surface plasmons; superconducting detectors; semiconductor quantum dots; nanophotonics  
  Abstract Surface plasmon polaritons (plasmons) have the potential to interface electronic and optical devices. They could prove extremely useful for integrated quantum information processing. Here we demonstrate on-chip electrical detection of single plasmons propagating along gold waveguides. The plasmons are excited using the single-photon emission of an optically emitting quantum dot. After propagating for several micrometers, the plasmons are coupled to a superconducting detector in the near-field. Correlation measurements prove that single plasmons are being detected.

  Title Comparison of timing jitter between NbN superconducting single-photon detector and avalanche photodiode Type Journal Article
  Year (down) 2010 Publication Phys. C Abbreviated Journal Phys. C  
  Volume 470 Issue 20 Pages 1534-1537  
  Keywords SSPD; APD; jitter  
  Abstract We report the pulse-to-pulse timing jitter measurement of a niobium nitride (NbN) superconducting single-photon detector (SSPD) and an InGaAs avalanche photodiode (APD) at 1550-nm wavelength. A direct comparison of their timing jitter was performed by using the same experimental configuration to measure both detectors. The measured jitter of the SSPD and the APD are 75 and 84 ps at full-width at half-maximum (FWHM), and 138 and 384 ps at full-width at tenth-maximum (FWTM), respectively. The jitter of the SSPD remains small at FWTM while that of APD is wide. We also estimated the transmission distances and secure key generation rates for fiber-based quantum key distribution (QKD) which uses these detectors. The estimated transmission distances of the APD are 86 km and 107 km with respect to 1 ns and 100 ps time windows, respectively, and those of the SSPD are 125 km and 172 km with respect to 1 ns and 100 ps time windows, respectively. This estimation indicates the SSPDЃfs advantages for QKD compared to the APD.

  Title Demonstration of single-flux-quantum readout operation for superconducting single-photon detectors Type Journal Article
  Year (down) 2010 Publication Applied Physics Letters Abbreviated Journal Appl. Phys. Lett.  
  Volume 97 Issue 11 Pages 3  
  Keywords SSPD  
  Abstract A readout circuit using superconducting single-flux-quantum (SFQ) circuits has been developed to realize an independently addressable array of superconducting single-photon detectors (SSPDs). We tested the SFQ readout circuits by connecting with SSPDs. The error rates of readout circuits were below 10–5 for input signal amplitude of greater than 18.2 μA. Detection efficiencies (DEs) for single-photon incidents were measured both with and without the connection of a readout circuit. The observed DEs traced almost the same curves regardless of the connection of the readout circuit, except that the SSPD is likely to latch by connecting the readout circuit.

  Title Nanowire superconducting single-photon detectors on GaAs for integrated quantum photonic applications Type Journal Article
  Year (down) 2010 Publication Applied Physics Letters Abbreviated Journal Appl. Phys. Lett.  
  Volume 97 Issue 15 Pages 3  
  Keywords SSPD  
  Abstract We demonstrate efficient nanowire superconducting single photon detectors (SSPDs) based on NbN thin films grown on GaAs. NbN films ranging from 3 to 5 nm in thickness have been deposited by dc magnetron sputtering on GaAs substrates at 350 °C. These films show superconducting properties comparable to similar films grown on sapphire and MgO. In order to demonstrate the potential for monolithic integration, SSPDs were fabricated and measured on GaAs/AlAs Bragg mirrors, showing a clear cavity enhancement, with a peak quantum efficiency of 18.3% at λ = 1300 nm and T = 4.2 K.

  Title Cверхпроводящий однофотонный детектор для дальнего ИК диапазона длин волн Type Conference Article
  Year (down) 2010 Publication Науч. сессия НИЯУ МИФИ Abbreviated Journal Науч. сессия НИЯУ МИФИ

  Keywords SSPD  
  Abstract Мы представляем быстродействующий сверхпроводниковый однофотонный детектор (SSPD) для дальнего инфракрасного диапазона на основе ультратонкой монокристаллической пленки NbN толщиной 3 нм, состоящий из параллельных полосок. QE на длине волны 1,5.μм и 1,3 μм для предложенного SSPD практически одинаковы. SSPD показывает отклик длительностью 200 пс, что открывает путь к детекторам, обладающим скоростью счета свыше 1 ГГц.
