Abstract
Probe field amplification through one-dimensional photonic crystal is investigated. Absorption and transmission properties of an incident probe pulse through one-dimensional photonic crystal are controlled by the quantum interference mechanism. It is shown that the quantum interference leads to phase control of the transmission and absorption behavior of a weak probe beam during its propagation through the one-dimensional photonic crystal. We further find that the gain without the population inversion can be achieved in the presence of doped atomic system at defect layer. In addition, the dynamical behavior of the probe field through the proposed medium is discussed, and the switching time of probe absorption to gain (or vice versa) is estimated.
