Abstract

A modified Welch-Costas (MWC) code family for the spectral-amplitude coding (SAC) optical code-division multiple-access (OCDMA) system is proposed. On utilizing the property of the MWC codes, more compact coder/decoders can be realized via waveguide and fiber gratings. In addition, this system has a superior performance as compared to the previous Walsh-Hadamard coded OCDMA system.
