“…Based on the strong coupling, the photons scattering properties in one-dimensional waveguide are extensively investigated and reviewed in [42]. Many quantum devices, such as single photon switching [16][17][18][19][20][21][22][23][24][25], router [36][37][38], isolation [43], transistor [35,44,45], frequency comb generator [46], and single photon frequency converter [34] have been proposed or realized. The one-dimensional waveguide can be photonic crystal waveguide [14], metal nanowire [5,6], superconducting microwave transmission lines [10,11], fiber [12], and diamond waveguide [15].…”

We investigate single photon scattering properties in one-dimensional waveguide coupled to quantum emitter's chain with dipole-dipole interaction (DDI). The photon transport is extremely sensitive to the location of the evanescently coupled emitters. The analytical expressions of reflection and transmission amplitudes for the chain containing two emitters with DDI are deduced by using real-space Hamiltonian. Two cases, where the two emitters symmetrically and asymmetrically couple to the waveguide, are discussed in detail. It shows that the reflection and transmission typical spectra split into two peaks due to the DDI. The Fano minimum in the spectra can also be used to estimate the strength of the DDI. Furthermore, the DDI makes spectra strongly asymmetric and create a transmission window in the region where there was zero transmission. The scattering spectra for the chain consisting of multi-emitters are also given. Our key finding is that DDI can broaden the frequency band width for high reflection when the chain consists of many emitters

“…In the following, we compare the single photon scattering properties of the second order nonlinear system with the one-dimensional CRW coupling to a two-level system [1], here we set U = 0, the current system has the same Hamiltonian form as the two-level system, but the eigenstate of the two system are different, the eigenstate of the latter system can be written as = ω e = 3 for second-order nonlinear system and the the two-level system. Where the black solid line denotes the second-order nonlinearity system and the red dotted line denotes the two-level system.…”

“…The contribution of the present scheme can be summarized as: (i)For the first time introduce the Kerr-nonlinearity into the CRW to realize the quantum optical switch. (ii) In comparison with the CRW coupling to a two-level system [1], which find that under the same parameters, the second-order nonlinear system can forms two perfect reflection regions, it is different from the perfect reflection dips formed by the two-level system. (iii) The case of both of the two-level atom and Kerr-nonlinearity are excited in the system, the Kerr nonlinearity can also be used as a single photon switch to control a single photon to realize transmission and reflection.…”

We study controllable single photon scattering in a onedimensional waveguide coupling with an additional cavity by second order nonlinear materials in a non-cascading configuration, where the additional cavity is embedded with two-level atom and filled with Kerr-nonlinear materials. Considering the second order nonlinear coupling, we analyze the transmission properties of the three different coupling forms as follows: (i) The two-level atom is excited without the Kerr-nonlinearity. (ii)The Kerr-nonlinearity is excited without the two-level atom. (iii) Both of the two-level atom and Kerr-nonlinearity are excited. The transmission and reflection amplitudes are obtained by the discrete coordinates approach for the three cases. The results showed that the transmission properties can be adjusted by the above three different coupling forms, which indicate our scheme can be used as a single photon switch to control the transmission and reflection of the single photon in the one-dimensional coupled resonant waveguide. We compared the results with [Phys. Rev. A 85, 053840(2012)] and find the advantages.

“…The coupled-resonator waveguide (CRW) with good scalability and integrability [2][3][4][5] provides an appropriate platform for studying quantum state transmission in quantum networks. Currently, single-photon transports in one-dimensional CRWs coupled to different kinds of quantum nodes are studied theoretically [6][7][8][9][10][11][12][13][14][15][16][17][18][19], and many important quantum devices are proposed, such as quantum switch [6][7][8][9][10][11][12][13][14], photon memory [15], single-photon router [16][17][18], and frequency converter [19]. In all these studies, the quantum devices based on CRWs are reciprocal.…”

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.
