Abstract

Recently, researches about the controllable group velocity of light propagation had made many progresses. And several experiments had demonstrated the signal evolution of slow and fast light. In this letter, the authors described a simple experiment for the tracing of light signals in an erbium-doped optical fiber at the optical communication wavelength firstly. We have, directly, observed the evolution of slow and fast signals with different waveforms that travel in an erbium-doped fiber amplifier. Through tracing the signal evolution, when slow light (Vg<

掺铒光纤中快慢光的信号演化

近年来，对光传播的可控群速度的研究取得了许多进展。几个实验已经证明了慢光和快光的信号演化。在这篇文章中，作者首先描述了一个简单的实验，用于在光通信波长上跟踪掺铒光纤中的光信号。我们已经直接观察到在掺铒光纤放大器中传播的具有不同波形的慢速和快速信号的演变。通过对信号演化的跟踪，当慢光(Vg<
