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.
