    摘要: A full width opto-mechanical modulator comprised of a silicon chip have dual rows or arrays of flexible finger-like reflectors disposed thereon in staggered facing relationship to one another. The reflectors, the surface of which is highly reflective, bend in response to the application of a predetermined potential. The modulator is placed in the path of a beam of high intensity light, and potentials applied to selected reflectors in accordance with an image signal input cause the modulator to reflect light striking the individual reflectors in either an exposure path or against a beam stop.

Epitaxially formed on this wafer is a GaAs/GaAlAs heterostructure with successive layers of Ga.sub.1-x Al.sub.x As-n, GaAs-p, and Ga.sub.1-y Al.sub.y As-p on the other surface, followed by an electrical contact layer of GaAs-p+ and an insulating layer of SiO.sub.2, discrete areas of the contact and insulating layers being removed by etching to form viewing windows for the individual LEDs, and with the area of the contact layer bordering the viewing windows being exposed and metallized to provide individual LED electrical contacts. In a second embodiment, the GaAs-p+ layer is dispensed with and the transparent electrically conducting coating is applied directly on both the insulating layer bordering the Ga.sub.1-y Al.sub.y As viewing windows and over the viewing windows. In a third embodiment, an edge emitting LED variant is provided and in a fourth embodiment, various light barrier designs are proposed for preventing optical crosstalk between the individual LEDs.
