  • Apparatus providing variable reflectivity to electromagnetic radiation
    Patent number: 6304362
    Abstract: An optically responsive variable reflecting surface uses a body of gallium held at a temperature slightly below its bulk melting point. Irradiation of the surface with optical energy produces substantial changes in surface reflectance. Devices employing gallium may be used for switching optical waveguides and in control of lasers.
