Abstract

Interest in nonlinear light-matter interaction in distributed feedback structure has considerably grown in the last years¹. The nonlinear spatio-temporal dynamics of the field in the periodic structures is qualitatively different from that both for the case of linear Bragg diffraction and the nonlinear interaction outside the diffraction condition. It has been predicted earlier² that gap soliton of self-induced transparency propagates at the Bragg frequency in discrete resonant structure, which consist of a set of ultrathin layers of two-level atoms.
