Scattering of a single photon in a one-dimensional coupled resonator waveguide with a Λ-type emitter assisted by an additional cavity
(color online) Single-photon reflectivity as a function of n when Δ = 0. The blue solid line is the reflectivity of the insert photon and the red dashed line is the reflectivity of the converted photon. Other parameters are the same as that in Fig.
