摘要
戒指配置提高的一根长光学地控制的延期线被基于刺激 Brillouinscattering 使用信号脉搏的组速度控制表明。在实验，二个光纤戒指洞被使用：一个人被用作 Brillouinlaser，提供单个模式司烧作为探查波浪飘动，其它被用作 Brillouinamplifier，作为慢光工作中等。我们用 ringBrillouin 放大器完成 215 ns 的最大的时间延期，比输入大的实时时间探查 40 ns 的脉搏宽度。同时，拓宽的可观的脉搏被观察，它基于线性理论与理论预言同意很好。
A long optically controlled delay line enhanced by ring configuration is demonstrated by using the group-velocity control of signal pulses based on stimulated Brillouin scattering. In experiment, two optical fibre ring cavities are used： one is used as the Brillouin laser, providing single-mode Stokes wave as probe wave; the other is used as the Brillouin amplifier, working as slow light medium. We achieve a maximum time delay of 215ns using the ring Brillouin amplifier, five times larger than the input probe pulse width of 40ns. In the meantime, a considerable pulse broadening is observed, which agrees well with the theoretical prediction based on linear theory.
