This paper discusses design, simulation, and experimental investigations of optical-code-division multiple-access (O-CDMA) networking using a spectral phase-encoded time spreading (SPECTS) method. O-CDMA technologies can potentially provide flexible access optical bandwidths in excess 1Tb/s without relying on wavelength- or time-division-multiplexing modules, provided that they overcome the interference caused by other users broadcasting over same channel, called multiuser (MUI). pursues...
