Photonic Coupling of Cold Molecules at Large Distances — •Harald R. Haakh, Sanli Faez, and Vahid Sandoghdar — MPI for the Science of Light, Erlangen, Germany

Recent theoretical studies have shown that tightly confined guided optical modes can facilitate the strong coupling of individual quantum emitters to these modes. In particular, plasmonic waveguides, tapered optical fibers and slot dielectric waveguides have been considered for such studies, whereby the latter have the advantage of not suffering from propagation loss.

In this presentation, we extend these platforms to the coherent interaction of several molecules at large separations via the guided mode of an optical fiber with a nanoscopic core diameter. We consider the interaction at strong and weak excitation and discuss how the high degree of control made possible by the large spatial dimensions allows for controlled switching of the nonlinear scattering of photon wave packets. Furthermore, we investigate the impact of dephasing in the solid state.
