  • Multichannel optical waveguide page scanner with individually addressable electro-optic modulators
    Patent number: 5418871
    Abstract: A mulitchannel optical waveguide page scanner has a diode laser and a primary optical channel waveguide. Light is coupled from the diode into the primary channel waveguide. Multiple secondary side channels each have a thin-film electro-optic waveguide modulator. A series of T-branch connectors distribute light from the primary channel to the secondary side channels. Each of the electro-optic waveguide modulators is addressable individually.
    Type: Grant
    Filed: August 23, 1994
    Date of Patent: May 23, 1995
    Assignee: Eastman Kodak Company
