Abstract

We present a technique for improving the pulse-delay performance of a stimulated Brillouin scattering (SBS) based broadband slow-light system by combining it with fiber Bragg gratings (FBG). We optimize the physical device parameters of three systems: (1) broadband SBS, (2) broadband SBS+a single FBG, and (3) broadband SBS+a double FBG for maximizing the delay performance. The optimization is performed under distortion and system resource constraints for a range of bit rates from 0.5 to 8.5Gbps. We find that an optimized broadband SBS+a double FBG system improves the fractional delay 1.8 times that of the broadband SBS system at an optimum bit rate of 3Gbps. Also, pump power consumption is reduced by 15% as compared to the broadband SBS system at the same bit rate.
