Phys. Rev. Lett. 89, 143602 (2002) [4 pages]Manipulating Light Pulses via Dynamically Controlled Photonic Band gapReceived 12 May 2002; published 16 September 2002 When a resonance associated with electromagnetically induced transparency in an atomic ensemble is modulated by an off-resonant standing light wave, a band of frequencies can appear for which light propagation is forbidden. We show that dynamic control of such a band gap can be used to coherently convert a propagating light pulse into a stationary excitation with nonvanishing photonic component. This can be accomplished with high efficiency and negligible noise even at the level of few-photon quantum fields thereby facilitating possible applications in quantum nonlinear optics and quantum information. © 2002 The American Physical Society URL:
