Abstract
A plurality of Acoustic Optic Modulators(AOM) are employed in the transmission subsystem of an optical data communication system for modulating different wavelengths of laser received from a grating with an electrical or radio frequency signal containing data or information to be transmitted. The modulated wavelengths of light associated with each AOM are recombined to form a shaped laser beam via a grating prior, and the shaped beams of laser light are multiplexed together for transmission over a fiber optic cable. A receiving station includes an optical decoding system for demultiplexing the shaped laser pulses, and for each shaped laser pulse detecting the individual modulated wavelengths of light comprising a desired spectrum, for extracting the data or desired information contained in each channel or wavelength of interest.
