Title Ultrafast superconducting single-photon detector Type Journal Article
Year (up) 2009 Publication J. Modern Opt. Abbreviated Journal J. Modern Opt.
Volume 56 Issue 15 Pages 1670-1680
Keywords SSPD, SNSPD
Abstract The state-of-the-art of the NbN nanowire superconducting single-photon detector technology (SSPD) is presented. The SSPDs exhibit excellent performance at 2 K temperature: 30% quantum efficiency from visible to infrared, negligible dark count rate, single-photon sensitivity up to 5.6 µm. The recent achievements in the development of GHz counting rate devices with photon-number resolving capability is presented.

Title Superconducting parallel nanowire detector with photon number resolving functionality Type Journal Article
Year (up) 2009 Publication J. Modern Opt. Abbreviated Journal J. Modern Opt.
Volume 56 Issue 2-3 Pages 334-344
Keywords PNR; SSPD; SNSPD; thin superconducting films; photon number resolving detector; multiplication noise; telecom wavelength; NbN
Abstract We present a new photon number resolving detector (PNR), the Parallel Nanowire Detector (PND), which uses spatial multiplexing on a subwavelength scale to provide a single electrical output proportional to the photon number. The basic structure of the PND is the parallel connection of several NbN superconducting nanowires (100 nm-wide, few nm-thick), folded in a meander pattern. Electrical and optical equivalents of the device were developed in order to gain insight on its working principle. PNDs were fabricated on 3-4 nm thick NbN films grown on sapphire (substrate temperature TS=900C) or MgO (TS=400C) substrates by reactive magnetron sputtering in an Ar/N2 gas mixture. The device performance was characterized in terms of speed and sensitivity. The photoresponse shows a full width at half maximum (FWHM) as low as 660ps. PNDs showed counting performance at 80 MHz repetition rate. Building the histograms of the photoresponse peak, no multiplication noise buildup is observable and a one photon quantum efficiency can be estimated to be QE=3% (at 700 nm wavelength and 4.2 K temperature). The PND significantly outperforms existing PNR detectors in terms of simplicity, sensitivity, speed, and multiplication noise.

Title A superconducting NbN detector for neutral nanoparticles Type Journal Article
Year (up) 2009 Publication Nanotechnol. Abbreviated Journal Nanotechnol.
Volume 20 Issue 45 Pages 455501
Keywords SSPD; SNSPD; *Electric Conductivity; Microscopy, Electron, Scanning; Nanoparticles/*chemistry/ultrastructure; Nanotechnology/*methods; *Photons
Abstract We present a proof-of-principle study of superconducting single photon detectors (SSPD) for the detection of individual neutral molecules/nanoparticles at low energies. The new detector is applied to characterize a laser desorption source for biomolecules and allows retrieval of the arrival time distribution of a pulsed molecular beam containing the amino acid tryptophan, the polypeptide gramicidin as well as insulin, myoglobin and hemoglobin. We discuss the experimental evidence that the detector is actually sensitive to isolated neutral particles.

Title Counting photons using a nanonetwork of superconducting wires Type Conference Article
Year (up) 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 High speed infrared photon counting with photon number resolving superconducting single-photon detectors (SSPDs) Type Conference Article
Year (up) 2009 Publication CLEO/Europe – EQEC Abbreviated Journal CLEO/Europe – EQEC
Volume Issue Pages
Keywords SSPD, SNSPD
Abstract A review of development and characterization of the nanostructures consisting of several meander sections, all connected in parallel was presented. Such geometry leads to a significant decrease of the kinetic inductance, without a decrease of the SSPD active area. A new type of SSPDs possess the QE of large-active- area devices, but, simultaneously, allows achieving short response times and the GHz-counting rate. This new generation of superconducting detectors has another significant advantage for quantum key distribution, they have a photon number resolving capability and can distinguish more photons.
