Abstract
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, and a self-damped electromechanical conformal grating disposed in the predetermined path, the self-damped electromechanical conformal grating. The self-damped electromechanical conformal grating includes an elongated ribbon element including a light reflective surface, a substrate and a pair of end supports for supporting the elongated ribbon element at both ends over the substrate; and at least one intermediate support between the end supports so that there are deformable portions of the elongated ribbon element above and movable into a channel containing a gas.
