Coherent Transport of Single Photon in a Quantum Super-cavity with Mirrors Composed of -Type Threelevel Atomic Ensembles

In this paper, we study the coherent transport of single photon in a coupled resonator waveguide (CRW) where two threelevel ?-type atomic ensembles are embedded in two separate cavities. We show that it is possible to control the photon transmission and reflection coefficients by using classical control fields. In particular, we find that the total photon transmission and reflection are achievable. In addition, the two atomic ensembles can act as controllable mirrors of a secondary cavity (super-cavity) which represents localized photon states and makes it possible to store and retrieve single photon in the region sandwiched between the two atomic ensembles.
