A. author Domínguez-Adame Acosta, Francisco author Malyshev, Andrey author 2019-03-14 We propose an efficient single-photon router comprising two resonator waveguide channels coupled by several sequential cavities with embedded three-level atoms. We show that the system can operate as a perfect four-way single-photon switch. We also demonstrate that an incident single photon propagating in one of the waveguides can be routed into one or the other output channels; such routing can be controlled by the external classical electromagnetic field driving the atoms. We argue that, under appropriate conditions, the efficiency of such routing can be close to 100% within a broad operational bandwidth, suggesting various applications in photonics. 2469-9926 10.1103/PhysRevA.99.033827 https://hdl.handle.net/20.500.14352/13310 http://dx.doi.org/10.1103/PhysRevA.99.033827 https://journals.aps.org Tunable single-photon quantum router
