Secure optical multiplex communication system

摘要

The communication system includes a holographic system to provide a plurality of spatially multiplexed optical beams each modulated by a different one of a plurality of binary intelligence signals. The plurality of modulated spatially multiplexed optical beams are coherently transmitted on an optical waveguide to a hologram and an array of photosensors to recover each of the intelligence signals. The waveguide may be an optical fiber of the parabolic index type to coherently transmit all of the plurality of modulated spatially multiplexed optical beams, or a plurality of single mode step index optical fibers each coherently transmitting a different one of the plurality of modulated spatially multiplexed optical beams.
