However, due to the low SBS threshold and relatively high realistic signal power, the gain in the usual SBS systems is limited at^30 dB. This paper presents a high-gain SBS scheme to realize large delay slow-light, which benefits from avoiding the depletion of the pump power in a short fiber as SBS media. The experiment demonstrates that, up to 50 dB non-saturated gain has been observed in the single-stage 591.8 m fiber SBS amplification. The slow-light delay can be obtained 52 ns, and the fractional delay can exceed 1.展开更多
