Abstract: A plasmonic transducer includes at least two metal elements with a gap therebetween. The metal elements are elongated along a plasmon-enhanced, near-field radiation delivery axis. Cross sections of the metal elements in a plane normal to the delivery axis vary in shape along the delivery axis. A waveguide is disposed along an elongated side of the plasmonic transducer. The waveguide is optically coupled to the plasmonic transducer along the elongated side.

Abstract: An apparatus includes a waveguide core having an elongated edge parallel to a substrate plane of the apparatus. An output end of the waveguide core faces a media-facing surface of the apparatus. A plate-like portion of a plasmonic material has a major surface facing the elongated edge of the waveguide core, and the major surface has a narrowed output end facing the media-facing surface. An elongated ridge of the plasmonic material is disposed on at least part of the plate-like portion between an input end and the narrowed output end.
