  Title Directional control of light by a nano-optical Yagi–Uda antenna Type Journal Article
  Year 2010 Publication Nature Photonics Abbreviated Journal Nat. Photon.  
  Volume 4 Issue (up) Pages 312 - 315  
  Keywords optical antennas  
  Abstract The plasmon resonance of metal nanoparticles can direct light from optical emitters in much the same way that radiofrequency antennas direct the emission from electrical circuits. Recently, rapid progress has been made in the realization of single-element antennas for optical waves. Because most of these devices are designed to optimize the local near-field coupling between the antenna and an emitter, the possibility of modifying the spatial radiation pattern has not yet received as much attention. In the radiofrequency regime, a typical antenna design for high directivity is the Yagi–Uda antenna, which essentially consists of a one-dimensional array of antenna elements driven by a single feed element. By fabricating a corresponding array of nanoparticles, similar radiation patterns can be obtained in the optical regime. Here, we present the experimental demonstration of directional control of radiation from a nano-optical Yagi–Uda antenna composed of appropriately tuned gold nanorods.

  Title Superconducting circuits: Quantum phase slips Type Journal Article
  Year 2010 Publication Nature Physics Abbreviated Journal Nat. Phys.  
  Volume 6 Issue (up) Pages 565–566  
  Keywords fromIPMRAS  
  Abstract Coulomb interactions can cause a rapid change in the phase of the wavefunction along a very narrow superconducting system. Such a phase slip at the quantum level is now measured in a chain of Josephson junctions.

  Title Monolithic InP multi-wavelength coherent receiver Type Conference Article
  Year 2010 Publication Conference on optical fiber communication, collocated national fiber optic engineers conference Abbreviated Journal Conf. OFC/NFOEC  
  Volume Issue (up) Pages 1-3  
  Keywords InP balanced detector, waveguide grating, polarization splitter, from chiralphotonics  
  Abstract We propose and demonstrate a novel four-channel monolithic polarization-diversity dual-quadrature coherent receiver with balanced detection in InP. It uses an interleave-chirped arrayed waveguide grating that acts simultaneously as a demultiplexer, 90° hybrid, and polarization splitter.

  Title Improved sensitivity of terahertz detection by GaAs photoconductive antennas excited at 1560 nm Type Journal Article
  Year 2010 Publication Appl. Phys. Lett. Abbreviated Journal Appl. Phys. Lett.  
  Volume 97 Issue (up) Pages 201110 (1-3)  
  Keywords photoconductive antenna (PCA)  
  Abstract The terahertz detection by photoconductive antennas (PCAs) based on low-temperature grown (LTG) GaAs with 1.5 μm pulse excitation was revisited. We found that the detection efficiency can be improved by a factor of 10 (20 dB) by reducing the excitation spot size and the gap length of the PCA, maintaining the low noise feature of the PCA on LTG GaAs. As a result, the signal-to-noise ratio higher than 50 dB was obtained at a reasonable incident power of 9.5 mW, suggesting that the scheme is promising for the detection of terahertz waves in practical time domain systems.

  Title THz communication system based on a THz quantum cascade laser and a hot electron bolometer Type Conference Article
  Year 2010 Publication 35th Int. Conf. Infrared, Millimeter, and Terahertz Waves Abbreviated Journal 35th Int. Conf. Infrared, Millimeter, and Terahertz Waves  
  Volume Issue (up) Pages 11623798 (1 to 2)  
  Keywords QCL, HEB detector  
  Abstract We present the experimental study of the direct emission – detection system based on the THz Quantum Cascade Laser as a source and Hot Electron Bolometer (HEB) detector – in view of its application as an optical communication system. We show that the system can efficiently transmit the QCL Terahertz pulses. We estimate the maximal modulation speed of the system to be about several GHz and show that it is limited only by the QCL pulse power supply, detector amplifier and connection line/wires parameters.
