We report on the control of the slow and fast light propagation velocity of two light beams (at 1550 nm and 980 nm) through an erbium doped fiber amplifier by means of coherent population oscillations. We modulate the amplitude of both beams with the same frequency so that the relative phase between both modulations allows us to control their group velocities. The same group velocity, in absolute value, is achieved when beams are modulated in phase or phase opposition. The experimental results are explained by a rate equation model.
