对单模光纤中宽带受激布里渊散射（SBS）慢光延迟进行了理论分析。利用两束宽带泵浦光可以构造平顶宽带SBS增益谱。提出了两种双宽带泵浦方案。我们发现，对于每一个方案，当相应地采用两个宽带泵浦光的适当结构时，总SBS增益的光谱轮廓变得宽而对称。我们的方案可以有效地减少甚至消除信号脉冲的展宽。它为慢光控制提供了更短的信号脉冲。
We describe a theoretical analysis of broadband stimulated Brillouin scattering (SBS) slow light delay in a single-mode optical fiber. A flat-top broadband SBS gain spectrum can be constructed by use of two broadband pump beams. We propose two schemes of the double broadband pumping. We show that, for each scheme, the spectral profile of the total SBS gain becomes wide and symmetric when the appropriate architecture of the two broadband pump beams is adopted accordingly. Our schemes can effectively reduce or even eliminate the broadening of signal pulse. It provides the use of shorter signal pulses for slow light control.
