| Abstract: | Propagation of an electromagnetic pulse through one-dimensional photonic
crystals with a three- level atomic defect layer is discussed. It is shown
that the group velocity of the transmitted pulse can be controlled by the
frequency detuning and the width of the defect layer. Moreover, the effects
of controlling parameter such as Rabi-frequency on light propagation through
one-dimensional photonic crystals are then introduced. |
