  Title Optoelectronic mixing in the NbN superconducting nanowire single photon detectors Type Conference Article
  Year 2009 Publication Proc. SPIE Abbreviated Journal Proc. SPIE  
  Volume 3786 Issue Pages 9  
  Keywords Optoelectronic devices, microwave superconductivity, nonlinearity, single photon detector, superconductivity, nanowire, optical mixing, microwave mixers, amplitude modulation, intensity modulation.  
  Abstract (down) In this paper, we present our experimental results on the electrically pumped optoelectronic mixing effect exhibited in a niobium nitride (NbN) superconducting nanowire. The experimental setup in order to test the mixer has been reported in detail. This superconductive nanowire optoelectronic mixer demonstrates photodetection and mixing in an integrated manner. We have explored both effects under a great variety of external conditions, such as temperature and bias current, in order to seek potential ways toward quantum optoelectronic detection and mixing by such nanowire device.

  Title Ultrafast nanowire superconducting single-photon detector with photon number resolving capability Type Conference Article
  Year 2009 Publication Proc. SPIE Abbreviated Journal Proc. SPIE  
  Volume 7236 Issue Pages 72360D (1 to 11)  
  Keywords PNR NbN SSPD, SNSPD, superconducting single-photon detectors, photon number resolving detectors, ultrathin NbN films  
  Abstract (down) In this paper we present a review of the state-of-the-art superconducting single-photon detector (SSPD), its characterization and applications. We also present here the next step in the development of SSPD, i.e. photon-number resolving SSPD which simultaneously features GHz counting rate. We have demonstrated resolution up to 4 photons with quantum efficiency of 2.5% and 300 ps response pulse duration providing very short dead time.

  Title Improved superconducting hot-electron bolometer devices for the THz range Type Conference Article
  Year 2004 Publication Proc. SPIE Abbreviated Journal Proc. SPIE  
  Volume 5498 Issue Pages 129-139  
  Keywords HEB mixer distributed model, numerical model  
  Abstract (down) Improved and reproducible heterodyne mixing (noise temperatures of 950 K at 2.5 THz) has been realized with NbN based hot-electron superconducting devices with low contact resistances. A distributed temperature numerical model of the NbN bridge, based on a local electron and a phonon temperature, has been used to understand the physical conditions during the mixing process. We find that the mixing is predominantly due to the exponential rise of the local resistivity as a function of electron temperature.

  Title Progress in far-infrared detection technology Type Conference Article
  Year 2002 Publication Proc. SPIE Abbreviated Journal  
  Volume 4795 Issue Pages 121-128  
  Keywords HgCdTe/CdTe, detector  
  Abstract (down) II-VI intrinsic very long wavelength infrared (VLWIR, λc~20 to 50 μm) materials, HgCdTe alloys as well as HgCdTe/CdTe superlattices, were grown by molecular beam epitaxy (MBE). The layers were characterized by means of X-ray diffraction, conventional Fourier transform infrared spectroscopy, Hall effect measurements and transmittance electron microscopy (TEM). Photoconductor devices were processed and their spectral response was also measured to demonstrate their applicability in the VLWIR region.

  Title NbN hot-electron bolometer as THz mixer for SOFIA Type Conference Article
  Year 2000 Publication Proc. SPIE Abbreviated Journal Proc. SPIE  
  Volume 4014 Issue Pages 195-202  
  Keywords NbN HEB mixers, airborne, stratospheric observatory, SOFIA  
  Abstract (down) Heterodyne receivers for applications in astronomy need quantum limited sensitivity. We have investigated phonon- cooled NbN hot electron bolometric mixers in the frequency range from 0.7 THz to 5.2 THz. The devices were 3.5 nm thin films with an in-plane dimension of 1.7 X 0.2 micrometers 2 integrated in a complementary logarithmic spiral antenna. The best measured DSB receiver noise temperatures are 1300 K (0.7 THz), 2000 K (1.4 THz), 2100 K (1.6 THz), 2600 K (2.5 THz), 4000 K (3.1 THz), 5600 K (4.3 THz), and 8800 K (5.2 THz). The sensitivity fluctuation, the long term stability, and the antenna pattern were measured. The results demonstrate that this mixer is very well suited for GREAT, the German heterodyne receiver for SOFIA.
