We present our recent results on the wave packet dynamics of coherent states in waveguiding structures coupled to artificial atoms. Physical realizations of such systems include coupled-resonator optical waveguides, defect structures in tailored nanophotonic media and microwave photonics in superconducting circuits.
The differences of the transport properties between a coherent state and a single-photon Fock state ([1]-[4]) in terms of various parameters such as the atom-photon coupling strength and the intensity of the light field is investigated numerically. Furthermore, quantum effects such as the atom-photon bound-state, which is a spatially localized, mixed excitation of light and matter, and nonlinear effects such as self-induced transparency that does not occur in the single-photon case are compared to the known results on single-photon excitations ([2]-[4]).
