Abstract

This paper presents a two-dimensional optical code-division multi-access (2D-OCDMA) system using multi-wavelength pulse modulation (MWPM), double optical hard-limiters (DHL) and modified carrier-hopping prime sequences (MCHP). Design criteria to reduce multi-access interference (MAI) are established and indicate that suitable signature sequences for 2D-OCDMA/MWPM must have good cross-correlation property in terms of both time-shift and wavelength-shift. Performance analysis of 2D-OCDMA/MWPM/DHL systems in presence of MAI and photo-detector shot noise is developed. Simulation and analytical results are in very good agreement and indicate that the proposed 2D-OCDMA/MWPM/DHL systems using MCHP sequences can offer a much larger capacity than others, suitable for applications in broadband multi-access optical networks
