我们展示了一种方法，以实现一个非常广泛和灵活的外部控制的群速度的信号，因为它们沿沿着光纤传播。这种控制是通过光纤本身中受激布里渊散射的增益和损耗机制来实现的。我们的实验表明，群速度低于71 000 km/s，远远超过了另一方面在真空中的光速，甚至负群速度可以很容易地获得一个简单的台式实验装置。我们相信，在标准单模光纤中，在正常的环境条件下，使用现成的仪器，可以实现慢光和快光的事实，是非常有前途的未来使用在真实的应用。(c)2005年美国物理学会。
We demonstrate a method to achieve an extremely wide and flexible external control of the group velocity of signals as they propagate along an optical fiber. This control is achieved by means of the gain and loss mechanisms of stimulated Brillouin scattering in the fiber itself. Our experiments show that group velocities below 71 000 km/s on one hand, well exceeding the speed of light in vacuum on the other hand and even negative group velocities can readily be obtained with a simple benchtop experimental setup. We believe that the fact that slow and fast light can be achieved in a standard single-mode fiber, in normal environmental conditions and using off-the-shelf instrumentation, is very promising for a future use in real applications.
