    We report on an all-in-fiber liquid crystal (LC) structure designed for the modulation of light incident transverse to the fiber axis. A hollow cavity flanked by viscous conductors is introduced into a polymer matrix, and ...
  • Lestoquoy, Guillaume; Wang, Zheng; Joannopoulos, John D.; Fink, Yoel; Chocat, Noemie (American Institute of Physics (AIP), 2013-04)
    We report on the fabrication of all-in-fiber capacitors with poly(vinylidene fluoride) (PVDF) as the dielectric material. Electrodes made of conductive polymer are separated by a PVDF thin film within a polycarbonate casing ...
  • del Alamo, Jesus A.; Wu, Joyce H. (Institute of Electrical and Electronics Engineers, 2010-05)
    We developed a through-substrate copper-damascene interconnect technology in silicon with minimal impedance. Via impedance was extracted using parameter measurements at 50 GHz that were matched to simple circuit models. ...
  • Daniilidis, N.; Narayanan, Siddharth Madhavan; Moller, S. A.; Clark, R.; Lee, T. E.; Leek, P. J.; Wallraff, A.; Schulz, Stephan Alf; Schmidt-Kaler, F.; Haffner, H. (Institute of Physics Publishing, 2011-01)
    We report heating rate measurements in a microfabricated gold-on-sapphire surface electrode ion trap with a trapping height of approximately 240 μm. Using the Doppler recooling method, we characterize the trap heating rates ...
  • Amadei, Carlo A.; Stein, Itai Y.; Silverberg, Gregory J.; Wardle, Brian L.; Vecitis, Chad D. (Royal Society of Chemistry, 2016-02)
    Here we report the synthesis of graphene oxide nanoscrolls (GONS) with tunable dimensions via low and high frequency ultrasound solution processing techniques. GONS can be visualized as a graphene oxide (GO) sheet rolled ...
  • Schattenburg, Mark Lee; Ahn, Minseung; Heilmann, Ralf K. (The International Society for Optical Engineering, 2008-07)
    We have developed a new type of soft x-ray diffraction grating. This critical-angle transmission (CAT) grating combines the advantages of traditional transmission gratings (low mass, extremely relaxed alignment and flatness ...
  • Herrault, Florian; Yen, Bernard C.; Ji, Chang-Hyeon; Spakovszky, Zoltan S.; Lang, Jeffrey H.; Allen, Mark G. (Institute of Electrical and Electronics Engineers (IEEE), 2010-02)
    This paper focuses on the design, fabrication, and characterization of silicon-packaged permanent-magnet (PM) microgenerators. The use of silicon packaging favors fine control on shape and dimensions in batch fabrication ...
  • Bright, V. M.; Anderson, D. Z.; Salim, E. A.; Chuang, H. C.; Vuletic, Vladan (Institute of Electrical and Electronics Engineers, 2009-10)
    This paper describes the design and fabrication of an atom chip for atom tunneling experiments. A fabrication process was developed that uses a combination of UV-optical and Electron-Beam lithography to pattern micrometer ...
  • Pacella, Nan Y.; Bulsara, Mayank; Drazek, Charlotte; Guiot, Eric; Fitzgerald, Eugene A. (Electrochemical Society, 2015-05)
