Abstract

A novel method of optical-code multiplex transmission from a central location is proposed. It has the advantages that the receivers can be configured to any channel quickly, the channels have in principle zero cross talk, and the bandwidth-expansion factors are less than for other optical-code-division multiple access arrangements. The proposed method is based on arrays of optoelectronic switching detectors that are at present under development for broadband matrix switching.
