  • Low-temperature infrared and raman spectra of the organic superconductor /spl kappa/(BEDT-TTF)Cu[N(CN)/sub 2/]Br, containing selected ISO topic substitutions of /sup 13/C and /sup 34/S, compared with normal-coordinate calculations

    Summary form only given. We will present measurements of the polarized infrared and Raman spectra, as a function of temperature, of single crystals of pure and isotopically-substituted /spl kappa/-(BEDT TTF)Cu[N(CN)/sub 2/)Br. The isotopically-substituted samples contain either /sup 13/C at the two central bond locations, or /sup 13/C at the six locations in the TTF framework, or /sup 34/S at the eight locations in the ET molecule. The measured frequency shifts will be used to aid in mode assignments and to refine the normal-coordinate calculations. Comparison between the infrared and Raman spectra will allow us to calculate electron-phonon couplings. The Raman spectra are obtained with a Fourier-Transform Raman spectrometer using an infrared laser. This reduces both the fluorescence background radiation and the possibility of photodegradation of the organic samples.

  • High speed infrared photon counting with photon number resolving superconducting single-photon detectors (SSPDs)

    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.

  • Registration of infrared single photons by a two-channel receiver based on fiber-coupled superconducting single-photon detectors

    Single-photon detectors (SPDs) are the foundation of all quantum communications (QC) protocols. Among different classes of SPDs currently studied, NbN superconducting SPDs (SSPDs) are established as the best devices for ultrafast counting of single photons in the infrared (IR) wavelength range. The SSPDs are nanostructured, 100 /spl mu/m/sup 2/ in total area, superconducting meanders, patterned by electron lithography in ultra-thin NbN films. Their operation has been explained within a phenomenological hot- electron photoresponse model. We present the design and performance of a novel, two-channel SPD receiver, based on two fiber-coupled NbN SSPDs. The receivers have been developed for fiber-based QC systems, operational at 1.3 /spl mu/m and 1.55 /spl mu/m telecommunication wavelengths. They operate in the temperature range from 4.2 K to 2 K, in which the NbN SSPDs exhibit their best performance. The receiver unit has been designed as a cryostat insert, placed inside a standard liquid-helium storage dewar. The input of the receiver consists of a pair of single-mode optical fibers, equipped with the standard FC connectors and kept at room temperature. Coupling between the SSPD and the fiber is achieved using a specially designed, precise micromechanical holder that places the fiber directly on top of the SSPD nanostructure. Our receivers achieve the quantum efficiency of up to 7% for near-IR photons, with the coupling efficiency of about 30%. The response time was measured to be <300 ps and it was limited by our read-out electronics. The jitter of fiber- coupled SSPDs is <35 ps and their dark-count rate is below 1 s/sup -1/. The presented performance parameters show that our single-photon receivers are fully applicable for quantum-correlation-type QC systems, including practical quantum cryptography.

  • Research on Conic Support in Radiant Cooler for Infrared Detector

    We have investigated the conic support In the radiant cooler for Infrared detector by using finite element method. Results show that the stiffness of the support increases with an increasing of the coning angle in case of launched state, while the situation is reversed in the orbited state. It is also found that the heat loss of the support caused by the thermal conduction decreases with the reduction of the coning angle. Moreover, the optimized coning angle is provided as a function of the thickness.

  • Material Characterization and Ultimate Performance Calculations of Compensated n-Type Silicon Bolometer Detectors at Liquid-Helium Temperatures

    The dependence of the resistivity and far infrared (FIR) absorptance on donor concentration, compensation, and temperature in compensated n-type Si is reported. The effect of environment, time constant, and spectral passband on the noise equivalent power (NEP) of the compensated Si bolometer is examined and compared with similar calculations for the compensated Ge bolometer.

  • High-T/sub c/ bolometers with silicon-nitride spiderweb suspension for far-infrared detection

    High-T/sub c/ GdBa/sub 2/Cu/sub 3/O/sub 7-/spl delta//(GBCO) superconducting transition edge bolometers with operating temperatures near 90 K have been made with both closed silicon-nitride membranes and patterned silicon-nitride (SiN) spiderweb-like suspension structures. As a substrate silicon-on-nitride (SON) wafers are used which are made by fusion bonding of a silicon wafer to a silicon wafer with a silicon-nitride top layer. The resulting monocrystalline silicon top layer on the silicon-nitride membranes enables the epitaxial growth of GBCO. By patterning the silicon-nitride the thermal conductance G is reduced from about 20 to 3 /spl mu/W/K. The noise of both types of bolometers is dominated by the intrinsic noise from phonon fluctuations in the thermal conductance G. The optical efficiency in the far infrared is about 75% due to a goldblack absorption layer. The noise equivalent power NEP for FIR detection is 1.8 pW//spl radic/Hz, and the detectivity D* is 5.4/spl times/10/sup 10/ cm /spl radic/Hz/W. Time constants are 0.1 and 0.6 s, for the closed membrane and the spiderweb like bolometers respectively. The effective time constant can be reduced with about a factor 3 by using voltage bias. Further reduction necessarily results in an increase of the NEP due to the 1/f noise of the superconductor.

  • Ultrafast Photoresponse Dynamics of Current-Biased Hg-Ba-Ca-Cu-O Superconducting Microbridges

    We report our time-resolved transient photoresponse studies of current-biased Hg-Ba-Ca-Cu-O superconducting microbridges excited by 100-fs-wide and 800-nm- wavelength laser pulses. Our devices consisted of 20-mum wide and 30-mum long bridges, incorporated into a 0.1-mm-wide signal line of the coplanar strip transmission line. The structures were patterned in 400-nm-thick precursor films grown on substrates by room-temperature magnetron sputtering and, subsequently, exposed to an <i>ex-situ</i> high-temperature mercuration process. The resulting structures consisted of a c-axis-oriented, predominantly Hg-1212 compound with the onset superconducting critical temperature T<sub>c,on</sub> around 110 K. At low temperatures (far below T<sub>c</sub> ), under low bias current and low optical excitation, the microbridge photoresponse signal was a positive, ~90-ps-wide (measurement- limited) pulse followed by a negative component and was related to the kinetic-inductive response. At high temperatures, or when the bias current was near the bridge critical current, we observed an additional slow resistive response due to the bolometric effect. The observed ultrafast photoresponse dynamics in our Hg-Ba-Ca-Cu-O bridges make this material very promising for optical photodetector and mixer applications.

  • Superconducting single photon detectors

    There is increasing interest in using superconducting optical photon detectors in a variety of applications. These applications require detectors that have extremely low dark count rates, high count rates, and high quantum efficiency. I will describe our work on two types of superconducting detectors, the Superconducting Nanowire Single Photon Detector (SNSPD or nSSPD) and superconducting Transition-Edge Sensor (TES). An SNSPD is an ultra-thin, ultra-narrow (nm scale) superconducting meander that is current biased just below its critical current density. When one or more photon is absorbed, a hot spot is formed that causes the superconductor to develop a resistance and consequently a voltage pulse. At NIST and JPL, we have been developing nanowire detectors using an amorphous alloy of tungsten-silicide. An example of this detector is shown in Fig 1(a). In this case, there are two tungsten silicide layers separated by a dielectric layer to optimize detection of light for any polarization[1]. Fig 1(b) is an example of a TES detector with gold cooling fins to enhance timing of the detector[2]. By exploiting the sharp superconducting-to-normal resistive transition of tungsten at 100mK, TES detectors give an output signal that is proportional to the cumulative energy in an absorption event. This proportional pulse-height enables the determination of the energy absorbed by the TES and the direct conversion of sensor pulse-height into photon number. I will discuss our progress towards developing both types of detectors with quantum efficiencies approaching 100%.
