Abstract :
We investigate the benefits of using time-gating detection in an optical code-division multiple access (OCDMA) system that comprises bipolar 64-chip long superstructure fiber Bragg grating encoders and decoders. Transmission of the codes is demonstrated, and it is shown that correlation combined with time-gating detection can provide some resilience to the distorting effects of dispersion, as well as the multiple access interference.
