英文摘要	In order to solve the problem that the stimulated Brillouin scattering fast light which occurs in the high absorption region decays rapidly, fast light via stimulated Brillouin scattering at double Brillouin gain line in an optical fiber is described and numerically simulated. The simulation results show that the fast light occurs between the double gain peaks induced by two pump waves when the frequency separation factor is at the range of 1-5.25, and the maximum time advancement is up to 25 ps between the doublet Brillouin lines when the frequency separation is 1.75. The double gain peaks can be observed when the frequency separation factor is larger than 0.596. The three-order dispersion (TOD) can complete compensation in the frequency separation factor range of 1-5.25. The dispersion relation can be represented by the normalized dispersion length Lm. As the separation factor is 2. 42, the Lm of TOD is infinite that expressed the TOD being fully compensated. The pulse broadening factor is 0.986 and the time advancement is 13. 52 ps at the separation factor of 2. 464. The pulse broadening factor is close to 1 when the frequency separation factor being larger than 2.464, and the time advancement is less than 13.52 ps. The research conclusions have certain theoretical significance for the realization of fast light in the Brillouin gain region, and have theoretical reference for designing optical devices based on stimulated Brillouin scattering fast light. © 2020, Science Press.
