High efficient single-photon router with six ports

With the assistance of three coupled cavity arrays with infinite length, which are crossed by coupling with two Δ-type three-level atoms, we propose a single-photon quantum router with six output ports. By solving the motion equation for the single-photon scattering numerically, where the affect of the atoms on the photon is written as the effective potentials, we find that the channel transfer rate can be larger than that with only one atom in the four output ports scheme.
