Two-dimensional all-optical parallel-to series TDM and demultiplexing by spectral-holographic methods

A two-dimensional all optical processor which multiplexes a rectangular array of parallel incoming signals into a series output transmitted through a single optical fiber is suggested for the first time along with a corresponding 2-dimensional series to parallel transformer. The system uses four-wave interaction in a hologram, both for MUX and deMUX. It can be used for the direct fiber-optical transmission of many time-dependent images, without going through the usual video serialization, as well as for multiple analog or digital, video and audio transmissions, or multiplexing and demultiplexing of any nature
