摘要

A resonant two level atom doped in one dimensional waveguide behaves as amirror, but this single-atom "mirror" can only reflect single photon perfectlyat a specific frequency. For a one dimensional coupled-resonator waveguide, wepropose to extend the perfect reflection region from a specific frequency to awide band by placing many atoms individually in the resonators in a finitecoordinate region of the waveguide. Such a doped resonator array promises us tocontrol the propagation of a practical photon wave packet with certain momentumdistribution instead of a single photon, which is ideally represented by aplane wave with specific momentum. The studies based on the discrete-coordinatescattering theory display that such hybrid structure indeed provides anear-perfect reflection for single photon in a wide band. We also calculatedphoton group velocity distribution, which shows that the perfect reflectionwith wide band exactly corresponds to the stopping light region.
