Abstract
The characteristics of small signal gain are studied in a one-dimensional periodically arranged amplifying media. It is proved that the small signal gain characteristics shows special features with the increase of gain material length. The variation in gain is determined by the mutual competition between the photonic band gap formed by the refractive index of amplifying media and gain reaction under the resonant Bragg condition. Furthermore, we investigated the gain on the parameters of excitons and resonant atoms.
