The minimum duration of pulses, that can be delayed through so called "slow light" in stimulated Brillouin scattering (SBS) is limited by the relatively narrow bandwidth of SBS (~15-30 MHz). This limits useful data rates to less than a few Mb/s while for telecommunication applications multi-Gb/s is required. We propose implementation of waveguide induced spectral broadening of SBS in optical fiber to allow massive increase of its bandwidth (reduction of operational pulse duration) to thereby achieve high data rate. Our analysis shows that for fiber of numerical aperture ~0.8 the SBS bandwidth is enhanced to ~15 GHz.
