    Abstract: An apparatus comprises a waveguide having an input end that receives energy in a transverse electric (TE00) mode from an energy source along a substrate-parallel plane. The apparatus also includes a near-field transducer located proximate an output end of the waveguide that receives the energy in the TE00 mode. The output end of the waveguide is at an oblique angle to a cross-track line at an intersection of a media-facing surface and the substrate-parallel plane. The near-field transducer includes an enlarged portion at the oblique angle to the cross-track line.

    Abstract: An apparatus including a waveguide input coupler, a tapered branch waveguide, and a waveguide adaptor physically connected to the waveguide input coupler proximal end and to the branch waveguide proximal end. The waveguide input coupler includes a distal end having a distal end width and a proximal end having a proximal end width. The tapered branch waveguide includes a distal end having a distal end width and a proximal end having a proximal end width, the branch waveguide distal end width being greater than the branch waveguide proximal end width. The waveguide input coupler, the branch waveguide, and the waveguide adapter are configured to convert input light having a base transverse waveguide mode to output light having a higher-order waveguide mode.

    Abstract: An approach for characterizing an optical near field transducer (NFT) involves providing excitation radiation to the NFT. The NFT emits photoluminescent radiation in response to the excitation radiation. The output radiation from the NFT is filtered so that a portion of the photoluminescent radiation emitted by the NFT passes through the filter and the excitation radiation is substantially blocked. A detector detects the portion of photoluminescent radiation and outputs an electrical signal in response to detection of the portion of photoluminescent radiation.

    Abstract: An apparatus includes a slider body, a laser diode, an optical path, and a heating element. The laser diode is configured to produce energy and is subject to temperature changes as a result of producing energy. The optical path within the slider body is configured to deliver the energy to heat a magnetic recording medium. The heating element is disposed along a length of the optical path within the slider body and is configured to control a temperature of the optical path to mitigate temperature-induced mode hopping of the laser diode.
