Paper Abstract
We present an experimental study of the second harmonic light generated at a slab of nonlinear molecules embedded in a 1D periodic structure, truncated by the introduction of a defect in the central period. We have observed an enhancement of the nonlinear interaction in the vicinity of the defect, when the second harmonic wave is excited for modes within the forbidden zone or stop band. We have also observed an enhancement near the band edge, where the group velocity approaches zero. Second harmonic generation is completely suppressed for local modes within the forbidden band other than the defect mode.
