    Abstract: An apparatus has an input surface configured to receive energy emitted from an energy source in a first mode. A mode order converter is configured to convert the energy from the first mode to a second mode. The waveguide of the apparatus has an input end disposed proximate the input surface and configured to receive the energy in the first mode. The waveguide has an output end disposed proximate a media-facing surface and configured to deliver energy in the second mode. The output end is at an oblique angle to a cross-track line at an intersection of the media-facing surface and a substrate-parallel plane.

    Abstract: An apparatus comprises a writer, a near-field transducer (NFT), a channel waveguide proximate the NFT, a dielectric layer between the NFT and waveguide, and a plurality of heat sinks. A first heat sink comprises a gap and contacts the NFT and the writer. A second heat sink extends across the gap of the first heat sink and between the NFT and a heat reservoir component, such as a return pole of the writer. The channel waveguide may contact the second heat sink, such as by encompassing a peripheral portion of the second heat sink. The second heat sink may have at least an outer surface comprising a plasmonic material, and may be configured to enhance plasmonic excitation of the NFT.

    Abstract: A heat-assisted magnetic recording head includes a near-field transducer, a waveguide, and a resonance enhancing feature. The near-field transducer is configured to focus and emit an optical near-field. The waveguide is configured to receive electromagnetic radiation and propagate the electromagnetic radiation toward and proximal to the near-field transducer. The resonance enhancing feature is disposed proximal to the near-field transducer and to a media-facing surface of the heat-assisted magnetic recording head. The resonance enhancing feature includes a first segment and a second segment disposed on opposite sides of the near-field transducer relative to a cross-track dimension of the heat-assisted magnetic recording head. Each of the first segment and the second segment of the resonance enhancing feature includes a liner and a filler. The liner of each of the first segment and the second segment at least partially faces the near-field transducer. The filler of each of the first segment and the second segment is disposed distal to the near-field transducer relative to the liner of the respective segment.

    Abstract: A write head includes a waveguide, a magnetic pole, and a near-field transducer. The near-field transducer includes an enlarged portion and a peg. The peg is separated from the magnetic pole in a downtrack direction by a dielectric gap. A peg coupler covers a bottom surface of the magnetic pole and is separated from the peg. The peg coupler is formed of a first plasmonic material. A pad extends from the peg coupler into part of the gap in the downtrack direction towards the peg. The pad is formed of a second plasmonic material and extends into the write head away from the media-facing surface a distance L that is less than a corresponding distance of the peg coupler.
