Dynamics of a single photon propagating in an inhomogeneously broadened medium — •Tom Schmit, Luigi Giannelli, and Giovanna Morigi — Theoretische Physik, Universität des Saarlandes, 66123 Saarbrücken, Germany

We theoretically analyze the evolution of a single photon propagating through a solid-state medium when the medium is inhomogeneously broadened in the longitudinal direction. Each atom of the medium is a three-level Λ system, where one transition couples to the electromagnetic field modes containing the single photon while the other is driven by an external laser field. The inhomogeneous broadening enters in the model as a position-dependent frequency shift Δ=Δ(z) of the excited state. We study the single-photon storage efficiency. Moreover, we determine the spectral and temporal properties of the transmitted photon as a function of the spatial distribution Δ(z).
