基于的悦耳的 stimulated-Brillouin-scattering (SBS ) 在光纤维慢光在未来在光缓冲有潜在的应用程序所有光的路由器交换系统。由于低 SBS 阀值和相对高的现实主义的信号力量,然而,在平常的 SBS 系统的获得在 ∼30 dB 被限制。这篇论文论述一个高获得的 SBS 计划认识到大延期慢光,它得益于作为 SBS 媒介在短纤维避免泵力量的弄空。实验表明那,直到 50 dB 非浸透的获得被观察了在单个阶段 591.8 m 纤维 SBS 扩大。慢光的延期能被获得 52 ns,和部分延期能超过 1。
Stimulated Brillouin scattering (SBS) has become a favorable underlying mechanism in many demonstrations of all-optical variable delay in standard fibers, often referred to as slow and fast light. Over 100 journal papers and numerous conference sessions have been dedicated to SBS slow light since 2005. In this paper, recent research in this area is reviewed. Following a short introduction to the topic, several specific trends in contemporary work are highlighted: the optimization of the SBS pump spectrum for extended slow light delay and reduced pulse distortion; SBS slow light demonstrations in nonstandard, highly nonlinear fibers; applications of SBS slow light to the delay of analog waveforms; and the role of polarization. Finally, a brief concluding perspective is provided.
