ABSTRACT:
A system and method for increasing channel capacity in fiber-optical communication networks utilizing space and time modulation. The system utilizes a three-dimensional spatial field of time division multiplexing, polarization modulation, and wavelength division multiplexing to increase channel capacity. A plurality of transmitter data processors receive a plurality of channel inputs for transmission over the optical network. The transmitter data processor produces time division multiplexing of a plurality of data channel inputs into a plurality of temporal and spatial data streams. A plurality of optical sources receive and directly modulated by the plurality of temporal data streams which are then polarization modulated before being delivered to a wavelength division multiplexer for transmission over an fiber-optics cable.
