受激布里渊散射（SBS）最近已被证明提供了一种机制，用于产生可调谐的全光延迟在室温单模光纤在电信波长。这种技术利用了在布里渊增益共振附近发生的折射率的快速变化。当慢光脉冲延迟受到可允许的脉冲失真的约束时，已经表明，相对于单线配置，使用一对紧密间隔的布里渊增益线可以增加失真约束的延迟。在本文中，我们的数值和实验表明，相同的实验装置通常用于产生一个布里渊增益偶极子，也可以用于实现三个等距布里渊增益谐振，进一步增加失真约束的脉冲延迟。
Stimulated Brillouin scattering (SBS) has been recently shown to offer a mechanism for generating tunable all-optical delays in room-temperature single-mode optical fibers at telecommunication wavelengths. This technique makes use of the rapid variation of the refractive index that occurs in the vicinity of the Brillouin gain resonance. When the slow light pulse delay is subject to a constraint on the allowable pulse distortion, it has been shown that the use of a pair of closely-spaced Brillouin gain lines can increase the distortion-constrained delay, with respect to the single-line configuration. In this paper, we numerically and experimentally demonstrate that the same experimental apparatus usually employed for generating a Brillouin gain doublet, can also be used for achieving three equally-spaced Brillouin gain resonances, further increasing the distortion-constrained pulse delay.
