在本文中,我们根据泵浦引起的与 Dy3+ 掺杂光纤中 6H15/2–6F11/2 跃迁相关的折射率和色散变化的观察结果,提出使用泵浦来降低或增加写入 Dy3+ 掺杂光纤中不同光栅参数的光纤布拉格光栅(FBG)中探测脉冲的群速度。我们讨论了泵浦功率、光纤光栅长度和掺杂浓度对群速度控制的影响。
In this paper, we propose to use a pump to decrease or increase the group velocity of a probing pulse in fiber Bragg gratings (FBG) with different grating parameters written into an Dy3+doped optical fiber based on the facts of the observations that pump-induced changes on the refractive index and dispersion associated with the6H15/2–6F11/2transition in Dy3+doped optical fiber. We discuss the effects of pump power, fiber grating length and doping concentration on the group velocity control.
