摘要

We demonstrate room temperature optically controllable group delay using population oscillation in an Er3+-doped fiber under a dual-frequency pumping laser. Using the numerical calculations, we study the effect of the pump power ratio (M) on the time delay and the group velocity of slow light propagation. The maximum time delay of 0.70 ms under a dual-frequency pump laser with two directions is obtained. Compared with a single pump method, the time delay can be increased with dual-frequency laser pumping. Moreover, we demonstrate clearly the influence of M on the maximum fractional delay and the optimal modulation frequency with an input signal power of 4.0 mW. (C) 2018 Optical Society of America
