Abstract

A novel coherent optical code-division multiple-access (OCDMA) network based on spectral phase coding and on phase and polarization diversity balanced reception is proposed. A rigorous model of the network is developed, which shows that spectral efficiencies of 1 bps/Hz and beyond can be achieved by minimizing multiple-access interference (MAI) and by canceling beat noise. While the system achieves full capacity under bit synchronism, it also offers competitive performance at up to 25% of full capacity, even when completely asynchronous. Tree and ring network configurations assure synchronization, making the proposed system robust in the presence of dispersion and phase noise.
