Numerical investigation of system performance in SBS slow light using filtered incoherent pump

Slow light based tunable delay line has been a potential enabler for all-optical networks. We numerically investigate the transmission performance incorporating the signal bandwidths into the incoherently pumped stimulated Brillouin scattering (SBS) slow light systems. Both the gain and loss part of the SBS spectrum are taken into account for more accurate comparison. Simulation results are illustrated in terms of the normalized delay and signal Q-factor products for both 2.5-Gb/s and 10-Gb/s on–off-keying (OOK) transmission systems. Optimization guidelines are given under different circumstances.
