Presentations

Gradient Index Subsurface Micro-Optics (FW2N.1)
Presenter: Lynford Goddard, Univ of Illinois at Urbana-Champaign

We present an overview of a new method to print 3D volumetric gradient index (GRIN) micro-optics inside a porous silica scaffold and show results for the focusing properties of an array of cylindrical GRIN lenses.

High Performance Silicon Flat Optics at Visible Wavelengths (FW2N.2)
Presenter: Arturo Burguete Lopez, King Abdullah Univ of Sci & Technology

We present a platform for the design of high efficiency flat optics. Experimentally, we show common components such as polarizers, dichroics, and color filters with over 99% efficiency in the visible in 50nm of silicon.

All-Optically Controlled Active Liquid-Crystal Plasmonic Metasurface Platform (FW2N.3)
Presenter: Mukesh Sharma, Tel Aviv University

We experimentally demonstrate all optically-controlled active liquid crystal (LC) plasmonic metasurface platform, based on laser induced nematic to isotropic (N-I) phase transition, which enables polarization switching in twisted NLC layer that controls the color of transmitted and reflected light.

Nanoelectromechanical Tuning of Dual-Mode Resonant Metasurfaces (FW2N.4)
Presenter: Tianzhe Zheng, California Institute of Technology

We demonstrate nanoelectromechanical tuning of dual-mode resonant dielectric metasurfaces. The devices achieve intensity modulation over 40%, >10kHz speed, and 144° phase shift with 7V bias voltage.

  Paper

Controlling All-Optical Switching Speeds in an Epsilon-Near-Zero Enhanced Metasurface (FW2N.5)
Presenter: Soham Saha, Purdue University

We propose a novel approach to control the speed of all-optical switches. In an epsilon-near-zero-metasurface comprising materials with picosecond- and nanosecond-switching-timescales, the switching-speed is controlled by the material interacting more strongly with the probe.

  Paper

Phase Tuning of Huygens Metasurfaces by Optical Anisotropy (FW2N.6)
Presenter: Ziwei Yang, Australian National University

We demonstrate phase-only tuning of optical metasurfaces in the full 2π-range by controlling the optical anisotropy of their surroundings. The concept is exemplified in a liquid crystal infiltrated metasurface tuned by the temperature and bias-voltage.

  Paper

Reconfigurable Unpatterned Metasurfaces via Acoustoelectric Gating of Graphene (FW2N.7)
Presenter: Amun Jarzembski, Sandia National Laboratories

Electric fields in a surface acoustic wave in a piezoelectric substrate can pattern charge in an adjacent graphene film via the acousto-electric effect and thus reconfigure the optical transmission in an unpatterned graphene metasurface.
