“…The photon pulse shape before and after the interaction can be calculated by Eqs. (19) and (20) and they are shown in Fig. 2(c) where the black solid curve is the incoming photon pulse while the red dotted curve is the reflected photon pulse and the blue dashed curve is the transmitted photon pulse.…”

“…In particular, a photon with frequency resonant to the two-level atom can be * zeyangliao@physics.tamu.edu † zubairy@physics.tamu.edu even completely reflected. Since then, this method has been generalized to the case for multilevel atom and multiphoton interactions [17][18][19][20][21][22]. In the stationary calculations, the photon is assumed to be a plane wave with single frequency.…”

We study the dynamics of a single-photon pulse traveling through a linear atomic chain coupled to a one-dimensional (1D) single mode photonic waveguide. We derive a time-dependent dynamical theory for this collective many-body system which allows us to study the real time evolution of the photon transport and the atomic excitations. Our analytical result is consistent with previous numerical calculations when there is only one atom. For an atomic chain, the collective interaction between the atoms mediated by the waveguide mode can significantly change the dynamics of the system. The reflectivity of a photon can be tuned by changing the ratio of coupling strength and the photon linewidth or by changing the number of atoms in the chain. The reflectivity of a single-photon pulse with finite bandwidth can even approach 100%. The spectrum of the reflected and transmitted photon can also be significantly different from the single-atom case. Many interesting physical phenomena can occur in this system such as the photonic band-gap effects, quantum entanglement generation, Fano-like interference, and superradiant effects. For engineering, this system may serve as a single-photon frequency filter, single-photon modulation, and may find important applications in quantum information.

“…Consequently, the photon transport property against the wave number when the atom is coupled to a waveguide with a nonlinear dispersion relation shows different behavior from that when the atom is coupled to a waveguide with a linear dispersion relation. Besides, the photon incident into the coupled-cavity waveguide has the group velocity v g = 2ξ sin k due to the nonlinear dispersion relation [22]. This may be used to realize the photon buffer [48].…”

We study controllable single-photon transport in a one-dimensional waveguide with a nonlinear dispersion relation coupled to a three-level emitter in a cascade configuration. An extra cavity field is introduced to drive one of the level transitions of the emitter. In the resonance case, when the extra cavity does not contain photons, the input single photon will be reflected; when the cavity contains one photon, the full transmission of the input single photon can be obtained. In the off-resonance case, the single-photon transport can also be controlled by the parameters of the cavity. Therefore, we show that single-photon transport can be controlled by an extra cavity field.

We study the transport of a single photon in two coupled one-dimensional semi-infinite coupled-resonator waveguides (CRWs), in which both end sides are coupled to a dissipative cavity. We demonstrate that a single photon can transfer from one semi-infinite CRW to the other nonreciprocally. Based on such nonreciprocity, we further construct a three-port single-photon circulator by a T-shaped waveguide, in which three semi-infinite CRWs are pairwise mutually coupled to each other. The single-photon nonreciprocal transport is induced by the breaking of the time-reversal symmetry and the optimal conditions for these phenomena are obtained analytically. The CRWs with broken time-reversal symmetry will open up a kind of quantum devices with versatile applications in quantum networks.
