  Title High resolution optical time-domain reflectometry using superconducting single-photon detectors Type Conference Article
  Year 2012 Publication Frontiers in Opt. 2012/Laser Sci. XXVIII Abbreviated Journal Frontiers in Opt. 2012/Laser Sci. XXVIII  
  Volume Issue Pages Fw3a.39  
  Keywords SSPD, SNSPD, Photodetectors; Fiber characterization; Light beams; Optical time domain reflectometry; Photon counting; Single mode fibers; Single photon detectors; Superconductors  
  Abstract We discuss the advantages and limitations of single-photon optical time-domain reflectometry with superconducting single-photon detectors. The higher two-point resolution can be achieved due to superior timing performance of SSPDs in comparison with InGaAs APDs.

  Title Superconducting NbN-nanowire single-photon detectors capable of photon number resolving Type Conference Article
  Year 2008 Publication Supercond. News Forum Abbreviated Journal Supercond. News Forum  
  Volume Issue Pages  
  Keywords PNR SSPD, SNSPD  
  Abstract We present our latest generation of ultra-fast superconducting NbN single-photon detectors (SSPD) capable of photon-number resolving (PNR). The novel SSPDs combine 10 μm x 10 μm active area with low kinetic inductance and PNR capability. That resulted in significantly reduced photoresponse pulse duration, allowing for GHz counting rates. The detector’s response magnitude is directly proportional to the number of incident photons, which makes this feature easy to use. We present experimental data on the performance of the PNR SSPDs. These detectors are perfectly suited for fibreless free-space telecommunications, as well as for ultra-fast quantum cryptography and quantum computing.

  Title Counting photons using a nanonetwork of superconducting wires Type Conference Article
  Year 2009 Publication Nano-Net Abbreviated Journal  
  Volume Issue Pages 120-122  
  Keywords SSPD, SNSPD  
  Abstract We show how the parallel connection of photo-sensitive superconducting nanowires can be used to count the number of photons in an optical pulse, down to the single-photon level. Using this principle we demonstrate photon-number resolving detectors with unprecedented sensitivity and speed at telecommunication wavelengths.

  Title Ultrafast and high quantum efficiency large-area superconducting single-photon detectors Type Conference Article
  Year 2007 Publication Proc. SPIE Abbreviated Journal Proc. SPIE  
  Volume 6583 Issue Pages 65830I (1 to 9)  
  Keywords SSPD, SNSPD, superconducting NbN films, infrared single-photon detectors  
  Abstract We present our latest generation of superconducting single-photon detectors (SSPDs) patterned from 4-nm-thick NbN films, as meander-shaped  0.5-mm-long and  100-nm-wide stripes. The SSPDs exhibit excellent performance parameters in the visible-to-near-infrared radiation wavelengths: quantum efficiency (QE) of our best devices approaches a saturation level of  30% even at 4.2 K (limited by the NbN film optical absorption) and dark counts as low as 2x10-4 Hz. The presented SSPDs were designed to maintain the QE of large-active-area devices, but, unless our earlier SSPDs, hampered by a significant kinetic inductance and a nanosecond response time, they are characterized by a low inductance and GHz counting rates. We have designed, simulated, and tested the structures consisting of several, connected in parallel, meander sections, each having a resistor connected in series. Such new, multi-element geometry led to a significant decrease of the device kinetic inductance without the decrease of its active area and QE. The presented improvement in the SSPD performance makes our detectors most attractive for high-speed quantum communications and quantum cryptography applications.

  Title High-speed and high-efficiency travelling wave single-photon detectors embedded in nanophotonic circuits Type Journal Article
  Year 2012 Publication Nat. Commun. Abbreviated Journal Nat. Commun.  
  Volume 3 Issue Pages 1325 (1 to 10)  
  Keywords waveguide SSPD  
  Abstract Ultrafast, high-efficiency single-photon detectors are among the most sought-after elements in modern quantum optics and quantum communication. However, imperfect modal matching and finite photon absorption rates have usually limited their maximum attainable detection efficiency. Here we demonstrate superconducting nanowire detectors atop nanophotonic waveguides, which enable a drastic increase of the absorption length for incoming photons. This allows us to achieve high on-chip single-photon detection efficiency up to 91% at telecom wavelengths, repeatable across several fabricated chips. We also observe remarkably low dark count rates without significant compromise of the on-chip detection efficiency. The detectors are fully embedded in scalable silicon photonic circuits and provide ultrashort timing jitter of 18 ps. Exploiting this high temporal resolution, we demonstrate ballistic photon transport in silicon ring resonators. Our direct implementation of a high-performance single-photon detector on chip overcomes a major barrier in integrated quantum photonics.
