Abstract

A scheme of tunable optical orthogonal encoder/decoder for all optical code division multiple access communication is proposed in this paper. It consists of a fiber splitter, a fiber combiner, N of 2 x 2 electro-optic switches and N of 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. The configuration of the proposed tunable encoder/decoder is simple and it is flexible for application. In addition, it has low optical power loss and easy in practical uses.
