Optical data modulation system with self-damped diffractive light modulator

摘要

A system for modulating a beam of light in accordance with an input data stream having a data rate greater than 2 MHz, includes a source of light for directing light along a predetermined path; a self-damped diffractive light modulator disposed in the predetermined path and having a plurality of spaced apart self-damped deformable elements being disposed relative to each other and secured at opposite ends and suspended above and movable into a channel containing a gas, and each spaced apart self-damped deformable element having at least one reflective surface. The spaced apart self-damped deformable elements respond to an input data stream and are sufficiently damped to minimize the introduction of data errors into the modulator light beam.
