Atom-photon interactions by a periodic atomic array is studied, when the scattering cross-section is increased either by an optical fiber or a cavity resonator. In the latter case, we consider a setup in which the atoms are driven by a laser and identify the conditions, under which the light at the cavity output exhibits nonclassical features. When the atoms form a periodic array confined, for instance, in a multimode hollow fiber [1,2], they can constitute a quantum nonlinear medium leading to the formation of spatial patterns of the propagating light. The coherence properties of the emitted light are determined and characterized for experimentally accessible parameters.
