Abstract
We present a method to improve the delay performance of stimulated Brillouin scattering (SBS) gain systems by combining them with Fabry-Perot (FP) filters under practical resource and data-fidelity constraints. We optimize the delay performance of four different systems: a single-line gain system (G1-system) combined with one FP filter (G1F1-system) and two FP filters (G1F2-system) and a double-line gain system (G2-system) combined with one FP filter (G2F1-system) and two FP filters (G2F2-system). We show that combining the gain-based slow-light system with FP filters can create a flat-top transmission spectrum and increases the phase slope. The G1F2-system provides a fractional delay 2.3 times that of the G1-system, whereas a G2F2-system improves the fractional delay 1.82 times that of the G2-system at a given bit rate under the same resource and data-fidelity constraints.
