A Study about Single-Photon Transport Controlled by the Three-Level Atom in the Optical Waveguide Cavity

Abstract

Through researching we can draw two conclusions. One conclusion is controlling the symmetric and asymmetric atomic - photon coupling interaction is a good way to control the transmission spectrum of incident light. Another conclusion is that multi-frequency photon attenuator can be controlled by asymmetric atomic - photon coupling interaction.

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 resonant photonic transport along optical waveguides by two-level atoms

Cong-Hua Yan, Lian-Fu Wei, W. Z. Jia +1 more

Recent works [Shen et al., Phys. Rev. Lett. 95, 213001 (2005); Zhou et al., Phys. Rev. Lett. 101, 100501 (2008)] showed that the incident photons cannot transmit along an optical waveguide containing a resonant two-level atom (TLA). Here we propose an approach to overcome such a difficulty by using asymmetric couplings between the photons and a TLA. Our numerical results show that the transmission spectrum of the photon depends on both the frequency of the incident photons and the photon-TLA couplings. Consequently, this system can serve as a controllable photon attenuator, by which the transmission probability of the resonantly incident photons can be changed from 0% to 100$%$. A possible application to explain the recent experimental observations [Astafiev et al., Science 327, 840 (2010)] is also discussed.

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.

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.

Emission of an atom inside a one-dimensional atomic cavity

Chaofan Zhou, Yusef Maleki, Zeyang Liao +1 more

We study the emission of a single-photon by a two-level emitter inside an atomic cavity consisting of two atomic mirrors coupled to a one-dimensional waveguide. With proper atomic separations, we realize a frequency comb as well as spectrum narrowing in the waveguide with the symmetric setting, and also unidirectional spectrum narrowing with asymmetric parameters. Within a suitable range, we can control the central frequency of the narrowed spectra by modulating atomic separations. Due to the collective interaction among the emitters, entanglement sudden birth and revival are observed between the mirrors.

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

Yu-Qing Zhang, Zhong-Hua Zhu, Zhao-Hui Peng +4 more

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.
