   Ultra-Fast Water-Based Terahertz Switches

   Presenter: Fabio Novelli, Ruhr University Bochum, Germany

    Presentation Details

   Invited

   Liquid water is often a problem in electronics because it causes damage or corrosion. On the contrary, concentrated aqueous solutions can be used as ultra-fast terahertz switches with a 20% modulation decaying in ~70 fs. As this liquid switch is faster than a thz cycle (~1 ps), it can be seen as a temporal boundary that clips the field and varies its frequency. The up-shifting from about 2 THz to 3 THz has an efficiency of 4%.This could open the door to the field of "water electronics".Authors: Fabio Novelli, Ruhr University Bochum

   An Explicit Formula for Electron-Hole Recollisions by Extreme Tailoring of Feynman Path Integrals

   Presenter: Qile Wu, University of California Santa Barbara, United States

    Presentation Details   Paper

   An explicit formula is derived for analysis of high-order sideband generation in a two-band model. We show the possibility of extracting information on band structures and dephasing rates from sideband signals with simple algebraic calculations.Authors: Qile Wu, University of California Santa Barbara / Mark Sherwin, University of California Santa Barbara

   Inter-Vortex Forward Brillouin Scattering by Chiral Flexural Phonons in Twisted Photonic Crystal Fibre

   Presenter: Xinglin Zeng, MPI for the science of light, Germany

    Presentation Details   Paper

   We report forward stimulated Brillouin scattering between orthogonal circularly polarized vortex modes in chiral photonic crystal fibre. The interaction is mediated by cork-screw-like flexural phonons, which provide both linear and orbital angular momentum.Authors: Xinglin Zeng, MPI for the science of light / Philip Russell, MPI for the science of light / Andreas Geilen, MPI for the science of light / Steven Becker, MPI for the science of light / Birgit Stiller, MPI for the science of light

   Ultranarrow-Linewidth Stimulated Intermodal Forward Brillouin Scattering

   Presenter: Wendao Xu, University of Rochester, United States

    Presentation Details   Paper

   We demonstrate strong (~300 W^-1 m^-1) and ultranarrow linewidth (~100 kHz) stimulated intermodal forward Brillouin scattering in a homogeneous few-mode fiber optical taper. This unique combination of parameters can enable record performance Brillouin-based microwave-photonic devices.Authors: Wendao Xu, University of Rochester / Maxime Zerbib, Université Bourgogne Franche-Comté / Arjun Iyer, University of Rochester / Jean-Charles Beugnot, Université Bourgogne Franche-Comté / William Renninger, University of Rochester

   Identification of Brillouin Lasing Modes in Silica Microspheres

   Presenter: Leticia Magalhaes, Harvard University, United States

    Presentation Details   Paper

   We explore a gated spectral measurement technique that, combined with group velocity dispersion measurements, enables the identification of the optical modes involved in Brillouin lasing in high optical mode density silica microspheres.Authors: Leticia Magalhaes, Harvard University / Gustavo Wiederhecker, State University of Campinas (UNICAMP) / Thiago Alegre, State University of Campinas (UNICAMP)

   (Withdrawn) Intracavity Highspeed Raman-Sampling of Coherent Terahertz Phonons Inside a Femtosecond Laser

   Presenter: Georg Herink, Universitat Bayreuth, Germany

    Presentation Details

   We reveal the origin of ultrashort Soliton molecules inside active cavities as Raman-stimulated Terahertz-phonons. Combining rapid laser-intrinsic soliton motion with real-time spectroscopy, we present time-domain Raman-sampling of THz phonons within record acquisition times.Authors: Alexandra Voelkel, Universitat Bayreuth / Luca Nimmesgern, Universitat Bayreuth / Adam Mielnik-Pyszczorski, Wroclaw University of Science and Technology / Timo Wirth, Universitat Bayreuth / Georg Herink, Universitat Bayreuth
