摘要：

We have demonstrated a surface plasmon polariton mediated optical Moire effect by inserting a silver slab between two subwavelength gratings. Enhancement of the evanescent fields by the surface plasmon excitations on the silver slab leads to a remarkable contrast improvement in the Moire fringes from two subwavelength gratings. Numerical calculations, which agree very well with the experimental observation of evanescent-wave Moire fringes, elucidate the crucial role of the surface plasmon polaritons. The near-field Moire effect has potential applications to extend the existing Moire techniques to subwavelength characterization of nanostructures. (c) 2007 Optical Society of America
