ABSTRACT:
An optical transducer includes an optical element for directing an electromagnetic wave to a focal region and a metallic nano-structure having a longitudinal axis non-parallel to an electric field of the electromagnetic wave. The optical element for directing an electromagnetic wave may comprise one of a solid immersion lens, a solid immersion mirror, or a planar waveguide. The metallic nano-structure may comprise a metallic pin. The metallic nano-structure may be structured and arranged for resonant coupling of energy into a recording medium.
