Abstract
We analyze the transition from slow to fast light upon increasing the modulation frequency based on coherent population oscillation in Cascaded Erbium-doped fiber structure. The change from slow to fast light is more obvious in the Cascaded structure. In this structure, the transition bandwidth is lager and the relative delay difference between the maximum fractional advancement and the maximum fractional delay is greater than that in the single-stage fiber.
