ABSTRACT:
An apparatus for focusing plasmon waves to a spot. The plasmon waves are there converted to light. In one application, the light is used for heat induced magnetic recording. In another application, the light is used as a part of near field scanning microscope. The plasmon waves may be induced on a converging rectangular cone having an aperture. The plasmon waves may also be focused on a flat surface by a curved dielectric lens. In the heat induced magnetic recording embodiment, a magnetic pole structure is integrated into the focusing apparatus, either as one surface of the rectangular cone, or as a layer upon which the curved dielectric lens is formed.
