Abstract

We investigate the single-photon propagation in the one-dimensional waveguide coupled to N two-level atoms. For a waveguide coupled to N distant atoms, the transparency can be induced by coherent interaction at resonance for an even number of N, while for an odd number of N, the photon can be fully reflected. We then can switch the photon transport by controlling the atomic number. For a waveguide coupled to a small atomic ensemble of N atoms in the same position, the transparency disappears, and the photonic transport property displays a jump behavior near the resonance point.
