Paper Abstract

By superposing two electric fields of light excited by s- and p-polarized light, respectively, it is possible to break the symmetry of the field intensity distribution in plasmonic crystals, which results in a DC voltage normal to the plane of incidence. Experimental results on 40 nm–thick Au film with square array of holes with diameter of 240 nm and period of 500 nm are compared with a numerical calculation based on the fast multipole boundary integral equation method. Dispersive behavior of transverse voltage around the surface plasmon resonance for circularly polarized light is elucidated in terms of the phase shift at the resonance.
