High-frequency light reflector via low-frequency light control Academic Article uri icon

abstract

  • 2015 American Physical Society. We show that the momentum of light can be reversed via the atomic coherence created by another light with one or two orders of magnitude lower frequency. Both the backward retrieval of single photons from a timed Dicke state and the reflection of continuous waves by high-order photonic band gaps are analyzed. The required control field strength scales linearly with the nonlinearity order, which is explained by the dynamics of superradiance lattices. Experiments are proposed with Rb85 atoms and Be2+ ions. This holds promise for light-controllable x-ray reflectors.
