   THz Detectors With Photoconductive Metasurfaces Operating at Microwatt Gate Power Levels

   Presenter: Lucy Hale, University College of London, United Kingdom

    Presentation Details   Paper  Add to Schedule

   We demonstrate terahertz (THz) detectors enabling high signal-to-noise ratio photoconductive detection at gate powers as low as 5μW. This is achieved by integrating a photoconductive metasurface, which enhances the detector efficiency and sensitivity.Authors: Lucy Hale, University College of London / Charles Harris, Sandia National Laboratories / Ting Shan Luk, Sandia National Laboratories / Sadhvikas Addamane, Sandia National Laboratories / John Reno, Sandia National Laboratories / Igal Brener, Sandia National Laboratories / Oleg Mitrofanov, University College of London

   Terahertz Beam Steering With Phase Change Based Metasurfaces

   Presenter: Zizwe Chase, University of Illinois at Chicago, United States

    Presentation Details   Paper  Add to Schedule

   We demonstrate dynamic control of beam steering applications using a phase change material, VO2, to form a combination of a series of terahertz meta-deflectors com�prised of geometrically optimized 2-gap split ring resonators supported on sapphire.Authors: Zizwe Chase, University of Illinois at Chicago / Riad Yahiaoui, University of Illinois at Chicago / Zhixiang Huang, University of Deleware / Xi Wang, University of Deleware / Thomas Searles, University of Illinois at Chicago

   Diffraction-Free Propagation of Terahertz Spoof
   Surface Plasmon Polaritons on Metasurfaces With
   Hyperbolic Dispersion

   Presenter: Sven Becker, TU Kaiserslautern, Germany

    Presentation Details   Paper  Add to Schedule

   We report the implementation of metasurfaces with hyperbolic dispersion thatroute propagating terahertz spoof surface-plasmon polaritons on highly confined, almostdiffraction-free signal paths. We also tuned their propagation angle by adjusting the hyperbolicisofrequency contour.Authors: Sven Becker, TU Kaiserslautern / Frederik Walla, Goethe-Universitaet Frankfurt / Hartmut Roskos, Goethe-Universitaet Frankfurt / Marco Rahm, TU Kaiserslautern

   Landau Polaritons in a Full-Dielectric Three-Dimensional Photonic-Crystal Cavity

   Presenter: Fuyang Tay, Rice University, United States

    Presentation Details   Paper  Add to Schedule

   We fabricated a full-dielectric three-dimensional photonic-crystal cavity containing an ultrahigh-mobility two-dimensional electron gas. By applying a strong perpendicular magnetic field, we created Landau polaritons originating from the ultrastrong coupling of electrons with cavity modes.Authors: Fuyang Tay, Rice University / Ali Mojibpour, Rice University / Shuang Liang, Purdue University / Andrey Baydin, Rice University / Arash Ahmadivand, Rice University / Nicolas Marquez Peraca, Rice University / Hongjing Xu, Rice University / Geoff Gardner, Purdue University / Michael Manfra, Purdue University / David Hagenmüller, Université de Strasbourg and CNRS / Junichiro Kono, Rice University

   Nonlinear Terahertz Photonics With Quantum Materials

   Presenter: Klaas-Jan Tielrooij, Catalan Institute of Nanoscience and Nanotechnology (ICN2), Spain

   Invited

   It has recently become evident that quantum materials with massless Dirac fermions have extremely strong terahertz nonlinearities. This talk will show how these can be enhanced even further, with interesting prospects for applications.Authors: Klaas-Jan Tielrooij, Catalan Institute of Nanoscience and Nanotechnology (ICN2)
