Abstract
|
Propagation of an electromagnetic pulse through one-dimensional photonic crystal doped with threelevel -type atomic systems is discussed. It is found that in the presence of quantum interference and incoherent pump, the transmitted pulse becomes completely phase dependent. So, the group velocity of the transmitted pulse can be switched from subluminal to superluminal light propagation just by adjusting the relative phase of applied fields.
