Multi-code keying scheme is proposed for spectral-amplitude coding (SAC) optical code-division multiple-access (OCDMA) network, and in this scheme users are assigned several signature sequences for spectral efficiency enhancement. The shifted prime codes can be used in this scheme since their code patterns are suitable for the implementation of compact encoding/decoding structures based on arrayed-waveguide gratings. The performance analysis shows that the proposed multi-code keying scheme obtains better spectral efficiency than previous two-code keying when number of codewords for each user is greater than two.
