Abstract
A communications transmitter is disclosed that utilizes a grating light valve (GLV) to impose information on an optical signal. The communications transmitter further includes at least one laser light source, a frequency dispersing device, an electrostatic modulator that serves as a GLV, and at least one data input source. The laser light source is configured to produce a light beam having a specific optical bandwidth and the frequency dispersing device is optically coupled to the light source and configured to disperse the light beam to produce a frequency dispersed light. The electrostatic modulator includes an electrostatically responsive reflective ribbon oriented to receive a portion of the frequency dispersed light having a specified bandwidth. The signal input source typically serves as an analog input source and is electronically coupled to each electrostatic modulator and is configured to cause electrostatic deformation of the reflective ribbon to modify the frequency of light received thereon to produce a modulated reflected light beam.
