Abstract
We present experimental results of second harmonic generation using a waveguide of PUSC deposited on a silver diffraction grating. The reflected second harmonic signal is enhanced at the angles of resonant excitation of the guided modes or of the surface plasmon. At these angles, we observe unexpected minima in the second harmonic signal, when the second harmonic frequency is situated within the absorption range of PUSC.
