Cavity optomechanics with sub-wavelength grating mirrors

Author(s)
Utku Kemiktarak, Mathieu Durand, Michael Metcalfe, John R. Lawall
We design, fabricate, and study a novel platform for cavity optomechanics: a silicon nitride membrane patterned as a sub-wavelength diffraction grating. Using...

Direct Measurement of Intrinsic Dirac Point and Fermi level at Graphene/Oxide interface and Its Band Alignment by Cavity Enhanced Internal Photoemission

Author(s)
Kun Xu, Caifu Zeng, Qin Zhang, Rusen Yan, Peide Ye, Kang Wang, Alan C. Seabaugh, Huili G. Xing, John S. Suehle, Curt A. Richter, David J. Gundlach, Nhan V. Nguyen
We report the first direct measurement of the Dirac point, the Fermi level, and the work function of graphene by performing internal photoemission measurements...

Spectroscopic Identification of Hydrogen Spillover Species in Ruthenium-modified High Surface Area Carbons by Diffuse Reflectance Infrared Fourier Transform Spectroscopy

Author(s)
Jeffrey L. Blackburn, Chaiwat Engtrakul, Justin B. Bult, Katherine Hurst, Yufeng Zhao, Qiang Xu, Philip A. Parilla, Lin J. Simpson, John-David R. Rocha, Matthew Ross Hudson, Craig Brown, Thomas Gennett
In recent years, carbon-based sorbents have been recognized for their potential application within vehicular hydrogen storage applications. One method by which...

Flux Lattices Reformulated

Author(s)
Ian B. Spielman, Gediminas Juzeliunas
We theoretically explore the optical flux lattices produced for ultra-cold atoms subject to laser fields where both the atom-light coupling and the effective...

Dual-polarization sensitive MKIDs for far infrared astrophysics

Author(s)
Johannes Hubmayr, James A. Beall, Daniel T. Becker, Hsiao-Mei Cho, Brad Dober, Mark Devlin, Anna E. Fox, Dale Li, Michael D. Niemack, David P. Pappas, Leila R. Vale, Kent D. Irwin, Gene C. Hilton
We present the design for arrays of dual-polarization sensitive, superconducting sensors for far infrared astrophysics. Each pixel is feedhorn-coupled and...

Indentation device for in situ Raman spectroscopic and optical studies

Author(s)
Yvonne B. Gerbig, Chris A. Michaels, Aaron M. Forster, John W. Hettenhouser, Walter E. Byrd, Dylan J. Morris, Robert F. Cook
Instrumented indentation is a widely used technique to study the mechanical behavior of materials at small length scales and thus has been exploited in...

Silicon Micromachines for Fun and Profit

Author(s)
David Bishop, Flavio Pardo, Cris Bolle, Randy Giles, Vladimir Aksyuk
Over the last decade or so a group of us, while working at Bell Labs, have been able to develop a large number of silicon micromachines for a wide range of...
