  • High speed erasing and rebiasing of thermoptic thin films in the medium and long-wave infrared
    Patent number: 4545641
    Abstract: Apparatus for rapidly erasing and rebiasing a thermoptic thin film in the near and medium infrared. A thermal insulating material (56) is disposed adjacent a thermoptic vanadium oxide thin film (50). The insulating layer has high transmittance in the 3-5 or 8-12 micrometer spectral bands. A layer of resistive semiconductor material (54) having high transmittance in the 3-5 or 8-12 micrometer band is disposed between the layer of insulating material and the vanadium oxide thin film. A multilayer dielectric thin film stack is superposed adjacent the vanadium oxide thin film, or is disposed in two parts adjacent the upper and lower surfaces of the thermoptic thin film.
