The diffraction of holographic gratings in a photorefractive iron-doped lithium niobate (LiNbO{sub 3}:Fe) crystal, on which surface a silver film was sputtered, was experimentally investigated. Besides the Bragg diffraction, an additional diffraction was observed. The experimental results present evidence of surface-plasmon-polariton (SPP) transmission through the silver film on the photorefractive substrate. The excitation of SPPs is speculated to be due to the corrugations of the silver film, which are caused by the photorefractive and the converse piezoelectric effect in the LiNbO3:Fe sample.
