    Abstract: A dual-slot waveguide receives energy from a coupling waveguide. The dual-slot waveguide includes first and second light propagating regions of low-index material located side-by-side in a direction normal to a light propagation direction. Inner sides of the first and second light propagating regions are separated by a first region of a high-index material. Second and third regions of the high-index material surround outer sides of the first and second light propagating regions. A near-field transducer receives portions of the energy from the first and second light propagating regions.

    Abstract: An apparatus includes a write pole proximate a media-facing surface of a recording head. A near-field transducer is adjacent to the write pole. A waveguide has a core layer extending from an energy source to the media-facing surface. The core layer includes a region of reduced downtrack thickness proximate the near-field transducer. The region of reduced downtrack thickness is defined by a notch facing away from the near-field transducer. A material of the notch has a different index of refraction than an index of refraction of the core layer.

    Abstract: A write head includes a near-field transducer near a media-facing surface of the write head and a waveguide. The waveguide includes a core that overlaps or is co-planer with the near-field transducer at a first region. The core has a second region extending away from the near-field transducer to an energy source. The core has a third region between the first and second regions. The third region has a third crosstrack width that is less than first and second crosstrack widths of the first and second regions.

    Abstract: A recording head has a near-field transducer that extends a first distance away from a media-facing surface. Two subwavelength focusing mirrors are at an end of a waveguide proximate the media-facing surface and extend a second distance away from the media-facing surface that is less than the first distance. The subwavelength mirrors are on opposite crosstrack sides of the near-field transducer and separated from each other by a crosstrack gap. The subwavelength focusing mirrors each include a first material at the media-facing surface and a plasmonic material that covers an edge of the subwavelength focusing mirror that faces the near-field transducer. The first material is more mechanically robust than the plasmonic material.
