Recent progress of optical CDMA technologies

A next generation passive optical network (NG-PON) becomes necessary to upgrade the systems, providing a larger dedicated bandwidth to each user. In this paper, we review our research activities carried out during the past five years over OCDMA system and its related technologies.
