利用双布里渊泵浦光纤中的受激布里渊散射实现了宽带慢光，其峰值在光谱上被两倍的布里渊频率分离。其中一个泵波产生的损耗谱被另一个泵波的增益谱完全补偿，这使得带宽可以扩大到25 GHz，并且对于37 ps脉冲，可变时间延迟高达10.9 ps。
Broadband slow light is demonstrated by using stimulated Brillouin scattering in optical fibers based on a double Brillouin pump, the peaks of which are spectrally separated by twice the Brillouin frequency. The loss spectrum generated by one of the pump waves is fully compensated by the gain spectrum of the other one, which permits the enlargement of the bandwidth to 25 GHz and a variable time delay of up to 10.9 ps with 37 ps pulses.
