Dependence of surface plasmon polarization conversion on the grating pitch.

A polarization conversion of linearly polarized light incident on a cross-corrugated metal surface may occur due to the optical energy exchange between the surface plasmon (SP) resonances at the metal-dielectric interface. In this paper, the angular and wavelength dependence of the SP-induced polarization conversion was studied in transmission as a function of the grating pitch of two perpendicular surface relief diffraction gratings. A theoretical model based on graphical representations in momentum space of the traveling light beam through the specimen was developed and successfully applied to the experimental results.
