Opto-electronic control of terahertz metamaterials


Conference Paper

We demonstrate external control of metamaterials operating at terahertz frequencies. Through photodoping of semiconducting substrates, used to support metamaterial arrays, we show ultrafast switching times. New metamaterial "grids" are presented, which may be formed by the union of electric metamaterials arrays. Metamaterial grids are then utilized to form a Schottky contact are used to demonstrate voltage switching of the metamaterials resonance. Both devices presented may be utilized to form novel devices at terahertz frequencies and also scaled to other energy regimes of interest.
