摘要：

Slow light is generated via the gain mechanisms of nonlinear optical phenomena- stimulated stimulated Brillouin scattering in optical fiber. Slow light is characterized in terms of Brillouin threshold, gain spectrum, Brillouin frequency shift by using optical heterodyne detection. According to the measured Brillouin frequency shift, we set our signal frequency in the gain region by manual matching method to get the maximum gain, and the gain bandwidth is broadened to 450MHz using a phrase-modulated pump. A delay of 32ns is achieved for the 500ns input signal when the gain is 15dB.
