英文摘要	The broadening Brillouin absorption spectrum of stimulated Brillouin scattering (SBS) in optical fibers by multiple monochromatic pumps is investigated. The results show that the bottom of the effective absorption spectrum becomes flatter with increasing the number of spectrum lines, and the spectral bandwidth is effectively expanded by multiple monochromatic pumps. but the spectral spacing should be tailored reasonably to ensure a broad linear range of the refractive index to reduce the pulse distortion. The time advancement and the pulse distortion induced by SBS pumped by broadband Gaussian and rectangular spectra are demonstrated respectively. The simulation results indicate that the pulse distortion induced by broadband rectangular spectral pump is smaller than that of broadband Gaussian spectral pump, and the time advancement can be improved effectively by increasing signal light power. We believe that these results are very promising for designing optical buffering or sensing components based on SBS fast light.
