title: Lattice solitons in self-defocusing optical media: analytical solutions of the nonlinear Kronig-Penney model.
abstract: A novel method for obtaining analytical solitary wave solutions of the nonlinear Kronig-Penney model in periodic photonic structures with self-defocusing nonlinearity is applied for providing generic families of solutions corresponding to the gaps of the linear band structure. Characteristic cases are shown to be quite robust under propagation.
