NEAR-FIELD TRANSDUCER |
| 摘要 |
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. |

1. An apparatus, comprising:
a waveguide core having an elongated edge parallel to a substrate plane of the apparatus, wherein an output end of the waveguide core faces a media-facing surface of the apparatus; a plate-like portion of a plasmonic material having a major surface facing the elongated edge of the waveguide core, wherein the major surface has a narrowed output end facing the media-facing surface and a narrowed input end facing away from the media-facing surface; and an elongated ridge of the plasmonic material disposed on at least part of the plate-like portion between the narrowed input end and the narrowed output end. |
