Optical properties of a waveguide-mediated chain of randomly positioned atoms

We theoretically study the optical properties of an ensemble of two-level atoms coupled to a one-dimensional waveguide. In our model, the atoms are randomly located in the lattice sites along the one-dimensional waveguide. The results reveal that the optical transport properties of the atomic ensemble are influenced by the lattice constant and the filling factor of the lattice sites. We also focus on the atomic mirror configuration and quantify the effect of the inhomogeneous broadening in atomic resonant transition on the scattering spectrum. Furthermore, we find that initial bunching and persistent quantum beats appear in photon-photon correlation function of the transmitted field, which are significantly changed by the filling factor of the lattice sites. With great progress to interface quantum emitters with nanophotonics, our results should be experimentally realizable in the near future.

Automated summary

We theoretically studied the optical properties of an ensemble of two-level atoms coupled to a one-dimensional waveguide, finding that the transport properties are affected by lattice constant and filling factor. Additionally, we observed initial bunching and quantum beats in the photon-photon correlation function of the transmitted field, which are significantly influenced by the filling factor of the lattice sites. Our results should be experimentally realizable in the near future with the advancement of interfacing quantum emitters with nanophotonics.
