Metallic nanostructures array has promising potential applications in nano-photonic devices based on surface plasmon resonance. In this letter, we report the fabrication of silver nanostructured grating pattern on periodically poled lithium niobate (PPLN) single crystal by the site-selective photo-deposition with UV-light irradiation. The microstructure of the silver nanostructured grating pattern on the positive domains was characterized by the DIC microscope and AFM. The SNOM characterization shows the enhancement of optical field due to the surface plasmon resonance (SPR) on silver NPs. Optical transmission spectra of silver nanostructured grating pattern show the silver NPs enhance the absorption.
