An integrated version of a total internal reflection (TIR) electrooptic spatial light modulator is described which utilizes a silicon integrated circuit as the drive electronics to address a 5376 element device. The integrated driver includes the addressing electronics, electrode drive circuitry, and electrodes, and is proximity coupled to the electrooptic crystal by pressing it against the crystal surface. The fringing fields from the electrodes on the silicon integrated circuit penetrate the electrooptic crystal, producing a line image with individually controlled intensity modulation between adjacent electrodes. This modulator, when coupled with an appropriate light source, can be used as an element for a xerographic printer or for writing on photographic film.
