Abstract

We investigate the single-photon transport properties in an optical waveguide coupled with a Λ-type three-level atom (ΛTLA) based on symmetric and asymmetric couplings between the photon and ΛTLA. The transmission and reflection coefficients of the single photon in such a hybrid system are deduced using the real-space approach. Symmetric and asymmetric bifrequency photon attenuators are realized by tuning the atom–photon couplings. The phase shift and group velocity delay of the transmitted single photon are also analyzed.

Controlling single-photon transport properties in a waveguide coupled with two separated atoms

Xiao Fei Zang, Tao Zhou, Bin Cai +1 more

Based on the symmetric, asymmetric atom–photon couplings and the phase difference between two separated atoms, single-photon transport properties in an optical waveguide coupled with two separated two-level atoms are theoretically investigated. The transmission and reflection amplitudes for the single-photon propagation in such a hybrid system are deduced via a real-space approach. Several new phenomena such as phase-coupled induced transparency, single-photon switches, symmetric and asymmetric bifrequency photon attenuators are analyzed. In addition, the dissipation effect of such a hybrid system is also discussed.

Manipulating Single-Photon Transport Properties in an Asymmetrical Waveguide Coupled to a Whispering-Gallery Resonator Containing a Two-Level Atom

Tao Zhou, Xiaofei Zang, Danhua Xu

A hybrid system containing an asymmetrical waveguide coupled to a whispering-gallery resonator embedded with a two-level atom is designed to investigate single-photon transport properties. The transmission and reflection amplitudes are obtained via the discrete coordinates approach. Numerical simulation demonstrates that a trifrequency photon attenuator is realized by controlling the couplings between the asymmetrical waveguide and the whispering-gallery resonator. The phase shift, group delay and dissipation effects of the transmitted single-photon are also discussed.

Controlling Single-Photon Transport along an Optical Waveguide by using a Three-Level Atom

Wei Tian, Bin Chen, XU Wei-dong

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.

Controlling single-photon transport in an optical waveguide coupled to an optomechanical cavity with a Λ-type three-level atom

Abstract We theoretically study the single-photon transport along a one-dimensional optical waveguide coupled to an optomechanical cavity containing a Λ-type three-level atom. Our numerical results show that the transmission spectra of the incident photon can be well controlled by such a hybrid atom-optomechanical system. The effects of the optomechanical coupling strength, the classical laser beam applied to the atom, atom-cavity detuning, and atomic dissipation on the single-photon transport properties are analyzed. It is of particular interest that an analogous double electromagnetically induced transparency emerges in the single-photon transmission spectra.

Controlling single-photon transport properties with asymmetrical waveguide-whispering-gallery resonator couplings

Tao Zhou, Xiaofei Zang, Yongsheng Liu +2 more

Asymmetrical waveguide-whispering-gallery resonator (WGR) couplings are proposed to manipulate single-photon transport properties in a hybrid system composed of a linear waveguide, a WGR and two separated two-level atoms. Tri-frequency/quadri-frequency photon attenuators and all-pass filters (caused by decoupling effects) are realized via the symmetrical/asymmetrical waveguide-WGR couplings and the phase difference induced by two atoms. The study of group delay shows slow-light and fast-light effects in this hybrid system, and dissipation effects imposing on the transmitted single photon are also analyzed.

We investigate theoretically the single-photon scattering by a Λ-type three-level system interacting with a whispering-gallery-type resonator which is coupled to a one-dimensional waveguide by full quantum-mechanical approach. The single-photon transmission amplitude and reflection amplitude are obtained exactly via real-space approach. The single-photon transport properties controlling by classic optical field are discussed. The critical coupling condition in the coupled waveguide-whispering-gallery resonator-atom with three-level system is also analyzed.
