K.; Smith, D.; Clark, D.; Thompson, R.; Bulsara, Mayank; Fitzgerald, Eugene A.; Drazek, C.; Guiot, E. (Institute of Electrical and Electronics Engineers, 2010-10)
    We present recent results on the direct heterogeneous integration of InP HBTs and Si CMOS on a silicon template wafer or SOLES (Silicon On Lattice Engineered Substrate). InP HBTs whose performance are comparable to HBTs ...
  • Shor, Peter W.; Smith, Graeme; Smolin, John A.; Zeng, Bei (Institute of Electrical and Electronics Engineers (IEEE), 2011-10)
    We construct families of high performance quantum amplitude damping codes. All of our codes are nonadditive and most modestly outperform the best possible additive codes in terms of encoded dimension. One family is built ...

    The in situ n-type doping of Ge thin films epitaxial grown on Si substrates is limited to 1 × 10[superscript 19] cm[superscript −3] by the phosphorous out-diffusion during growth at 600 °C. By studying the phosphorous ...
  • Wang, Tianyu Tom; Quatieri, Thomas F. (Institute of Electrical and Electronics Engineers, 2009-10)
    This paper considers the problem of obtaining an accurate spectral representation of speech formant structure when the voicing source exhibits a high fundamental frequency. Our work is inspired by auditory perception and ...

    An improved single-cell photonic band-gap (PBG) structure with an inner row of elliptical rods (PBG-E) was tested with high power at a 60 Hz repetition rate at X-band (11.424 GHz), achieving a gradient of 128  MV/m at a ...

    We demonstrate a high-peak-power, 1-kHz, 2.2-mum OPCPA for long-wavelength-driven high harmonic generation that produces 9-GW, 3-optical-cycle, CEP-stabilized pulses, allowing tunneling-ionization-threshold intensity with ...
  • Juodawlkis, Paul W.; Loh, William; O'Donnell, Frederick J.; Brattain, Michael A.; Plant, Jason J. (SPIE, 2010-02)
    For the past several years, we have been developing a new class of high-power, low-noise semiconductor optical gain medium based on the slab-coupled optical waveguide (SCOW) concept. The key characteristics of the SCOW ...
  • Grulkowski, Ireneusz; Liu, Jonathan Jaoshin; Potsaid, Benjamin M.; Jayaraman, Vijaysekhar; Jiang, James; Fujimoto, James G.; Cable, Alex E. (Optical Society of America, 2013-02)
    We demonstrate ultralong-range swept-source optical coherence tomography (OCT) imaging using vertical cavity surface emitting laser technology. The ability to adjust laser parameters and high-speed acquisition enables ...
  • Lee, Jungchul; Bryan, Andrea Kristine; Manalis, Scott R. (American Institute of Physics (AIP), 2011-02)
    An intrinsic uncertainty in particle mass sensing with the suspended microchannel resonator results from variation in a particle's position near the free end of the resonator. To circumvent this error we employ the second ...
  • Meyer, Harvey B. (American Physical Society, 2009-09)
    We compute the entropy density of the confined phase of QCD without quarks on the lattice to very high accuracy. The results are compared to the entropy density of free glueballs, where we include all the known glueball ...
  • Bond, Robert A.; Bliss, Nadya T.; Mullen, Julie; Kepner, Jeremy; Kim, Hahn G.; Reuther, Albert I. (Institute of Electrical and Electronics Engineers, 2009-02)
    In this paper, we explore the ease of tackling a communication-intensive parallel computing task - namely, the 2D fast Fourier transform (FFT). We start with a simple serial Matlab code, explore in detail a ID parallel ...
