  • Photorefractive effect in bulk chalcogenide glass and devices made therefrom
    Patent number: 5136677
    Abstract: The photorefractive effect results in a change in the refractive index of bulk chalcogenide glass when it is exposed to certain wavelengths of light, in particular, sub-band-gap light. The effect results in a variety of device structures including a fiber optic faceplate; an optical waveguide; a fiber tap; a lens and a Bragg grating. Methods for fabricating the various devices are described.
    Type: Grant
    Filed: June 6, 1991
    Date of Patent: August 4, 1992
    Assignee: Galileo Electro-Optics Corporation
    Inventors: Martin G. Drexhage, Lee M. Cook, Tracey L. Margraf, Cornelius T. Moynihan
