    We consider third harmonic generation in a periodic layered medium with alternate nonlinear media. We show enhanced third
    harmonic generation when the fundamental frequency matches one of the mode frequencies of the distributed feedback structure.
    The observed feature is explained in terms of large local field enhancement for the fundamental wave.
