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: A write head includes a near-field transducer near a media-facing surface of the write head. The write head includes a waveguide having a core with a first side disposed proximate to the near-field transducer. The core overlaps the near-field transducer at a substrate-parallel plane. The core includes one of a step or a taper on a second side facing away from the first side. The step or the taper causes a reduced thickness of the core normal to the substrate-parallel plane. The write head includes a cladding layer that encompassing the second side of the core and that fills in the step or the taper.

Abstract: An apparatus includes a waveguide that has a core between the first and second cladding layers. A near-field transducer in the first cladding layer is configured to receive the energy from the waveguide and deliver the energy to a recording medium. A reflector in the second cladding layer is configured to reduce reflection of the energy from the recording medium back to an energy source.

Abstract: An apparatus includes a write head comprising a near-field transducer at a media-facing surface of the write head and a waveguide extending along a light-propagation direction. The waveguide is configured to receive light emitted from a light source at a fundamental transverse electric mode. The waveguide is configured to deliver the light to the near-field transducer at a transverse magnetic mode which directs surface plasmons to a recording medium in response thereto. The waveguide comprises a core with first and second tapers separated by a straight portion of constant cross sectional width. The first and second tapers successively decrease a cross-sectional width of the core as it nears the near-field transducer. The waveguide includes an end portion between the second taper and the near field transducer. The end portion comprises a top cladding layer, aside cladding layer, and a bottom cladding layer on the side cladding layer.
