Abstract

A tunable optical orthogonal encoder/decoder is designed and realized by means of programmable memory, optical splitter and combiner, 2X2 optical switches and optical delay lines. It overcomes the poor correlation, small capacities and narrow tunable range of prime-code and 2n code tunable optical encoder /decoder found in the literature abroad. The configuration of the proposed encoder/decoder is simple and it is flexible for application. In addition, it has low optical power loss and very suitable for all-optical code-division multiple access communication system.
