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.
