  Title Spectrum of thermal fluctuation noise in diffusion and phonon cooled hot-electron mixers Type Journal Article
  Year 1998 Publication Applied Physics Letters Abbreviated Journal Appl. Phys. Lett.  
  Volume 72 Issue (up) 12 Pages 1516-1518  
  Keywords HEB mixer; thermal fluctuation noise; TFN  
  Abstract A systematic study of the intermediate frequency noise bandwidth of Nb thin-film superconducting hot-electron bolometers is presented. We have measured the spectrum of the output noise as well as the conversion efficiency over a very broad intermediate frequency range (from 0.1 to 7.5 GHz) for devices varying in length from 0.08 μm to 3 μm. Local oscillator and rf signals from 8 to 40 GHz were used. For a device of a given length, the spectrum of the output noise and the conversion efficiency behave similarly for intermediate frequencies less than the gain bandwidth, in accordance with a simple thermal model for both the mixing and thermal fluctuation noise. For higher intermediate frequencies the conversion efficiency decreases; in contrast, the noise decreases but has a second contribution which dominates at higher frequency. The noise bandwidth is larger than the gain bandwidth, and the mixer noise is low, between 120 and 530 K (double side band).

  Title Nanowire superconducting single-photon detectors on GaAs for integrated quantum photonic applications Type Journal Article
  Year 2010 Publication Applied Physics Letters Abbreviated Journal Appl. Phys. Lett.  
  Volume 97 Issue (up) 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 Waveguide superconducting single-photon detectors for integrated quantum photonic circuits Type Journal Article
  Year 2011 Publication Applied Physics Letters Abbreviated Journal Appl. Phys. Lett.  
  Volume 99 Issue (up) 18 Pages 181110(1-3)  
  Keywords optical waveguides, waveguide SSPD  
  Abstract The monolithic integration of single-photon sources, passive optical circuits, and single-photon detectors enables complex and scalable quantum photonic integrated circuits, for application in linear-optics quantum computing and quantum communications. Here, we demonstrate a key component of such a circuit, a waveguide single-photon detector. Our detectors, based on superconducting nanowires on GaAs ridge waveguides, provide high efficiency (~0%) at telecom wavelengths, high timing accuracy (~0 ps), and response time in the ns range and are fully compatible with the integration of single-photon sources, passive networks, and modulators.

  Title Two-state competition in 1.3 μm multilayer InAs/InGaAs quantum dot lasers Type Journal Article
  Year 2009 Publication Applied Physics Letters Abbreviated Journal Appl. Phys. Lett.  
  Volume 95 Issue (up) 19 Pages 3  
  Keywords 2DEG  
  Abstract The competition of ground state (GS) and excited state (ES) is investigated from the as-grown and thermally annealed 1.3 μm ten-layer p-doped InAs/GaAs quantum dot (QD) lasers. The modal gain competition between GS and ES are measured and analyzed around the ES threshold characteristics. Our results show that two-state competition is more significant in devices with short cavity length operating at high temperature. By comparing the as-grown and annealed devices, we demonstrate enhanced GS and suppressed ES lasing from the QD laser annealed at 600 °C for 15 s.

  Title Crystallization of implanted amorphous silicon during millisecond annealing by infrared laser irradiation Type Journal Article
  Year 2010 Publication Applied Physics Letters Abbreviated Journal Appl. Phys. Lett.  
  Volume 97 Issue (up) 2 Pages 3  
  Keywords Annealing  
  Abstract We investigated the homogenous nucleation of crystalline grains in amorphous Si during transient temperature pulse of few milliseconds IR laser irradiation. The crystallized volume fraction is ~80%. Significant crystallization occurs in nonsteady regime because of the rapid temperature variation (106 °C/s). Our model combines the time evolution of the crystal grain population with the consumption of the amorphous volume due to the growth of grains. Thanks to the experimental approach based on a laser source to heat α-Si and the theoretical model we extended the description of the spontaneous crystallization up to 1323 K or 250 K above the temperature investigated by conventional annealing.
