摘要We theoretically investigate the single-photon transport properties in an optical waveguide embedded with a V-type three-level atom (VTLA) based on symmetric and asymmetric couplings between the photon and the VTLA. Our numerical results show that the transmission spectrum of the incident photon can be well controlled by virtue of both symmetric and asymmetric coupling interactions. A multifrequency photon attenuator is realized by controlling the asymmetric coupling interactions. Furthermore, the influences of dissipation of the VTLA for the realistic physical system on single-photon transport properties are also analyzed.
