摘　　要：采用快速傅里叶变换算法,数值模拟了双泵浦宽带布里渊吸收谱的受激布里渊散射快光.模拟结果表明信号脉冲的时间提前、衰减和脉冲展宽因子容易受到两个泵浦光的相对频率分离因子、输入泵浦光的功率以及光纤长度的影响.优化设计频率分离因子、输入泵浦光的功率以及光纤长度,224ps高斯信号脉冲实现了80ps的最大提前量和0.87的最小展宽因子.研究结果可以提高光纤通信系统的数据速率,降低脉冲失真.Stimulated Brillouin scattering fast light based on doublet broadband Brillouin absorption resonances was numerically investigated by using fast Fourier transform algorithm. The simulation results show that the time advancement, attenuation and broadening factor of signal pulse are readily tailored by relative frequency separation factor of two pump, pump power and length of fiber. The maximum advancement of 80 ps and the minimum broadening factor of 0.87 are achieved for 224 ps Gaussian signal pulse by optimizing relative frequency separation factor of two pump light, power and length of fiber. These will lead to increase the data rate of optical system and reduce the pulse distortion.
