In this paper, we employ two two-level atoms and a Λ-type atom to connect two one-dimensional semi-infinite coupled resonator waveguides, respectively. The first configuration is a chiral setup, where incident photons undergo an elastic scattering process. We investigate the influence on the single-photon transfer rate of spatial coupling points between the small or giant atom and the waveguides.

Abstract We investigate quantum emitters (QEs) interacting with a photonic structured bath made of bilayer square lattices, where the resonance anticrossing between the energy bands opens a symmetric middle energy gap. Due to the intrinsic chiral symmetry of the bath and interactions with the squarelike band edges, the QE-photon dressed states generated in this inner band gap are odd neighbor, robust, and anisotropic, when the emitters' transition frequencies lie in the middle of the band gap.
