Abstract
The demand for efficient optical communication systems has fuelled considerable research in developing techniques for eradicating phase-induced intensity noise (PIIN) in spectral-amplitude coding optical code-division multiple-access (SAC-OCDMA). This paper investigates the use of modified-AND subtraction detection technique to mitigate PIIN in SAC-OCDMA systems.The simulation results show that the modified-AND subtraction detection demonstrates better performance over the conventional AND detection approach.Furthermore, we have found that, from a transmission length of 40 km onwards, group velocity dispersion (GVD) degrades SAC-OCDMA system performance apparently.Dispersion compensating fiber (DCF) is used to lessen the influence of GVD caused by single mode fiber (SMF).
