    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.

    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.
