  • Abstract
    Based on the equivalent phase shift (EPS) technology, the optical code-division multiple access (OCDMA) en/decoders employing multiple pi-EPSs have been studied both numerically and experimentally, which demonstrate good en/decoding performances. It is also shown that the insertion of multiple pi-EPSs offers a new degree of freedom for OCDMA security, in which the multiple pi -EPSs decoder is completely unmatched with single pi-EPSs encoder even if they have the same code sequence.
