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 method is provided for characterizing the peg region of a near-field transducer incorporated into a write head of a HAMR magnetic recorder. The method includes providing excitation radiation to one or more near-field transducers. The near-field transducers include an enlarged disk region and a peg region at least partially in contact with the enlarged disk region. The method further includes filtering output radiation from the near-field transducers by passing a portion of photoluminescent radiation emitted by the near-field transducers in response to the excitation radiation and substantially blocking the excitation radiation transmitted by the near-field transducers. The method also includes detecting the portion of photoluminescent radiation and characterizing the peg region of at least one of the plurality of near-field transducers.

Abstract: An apparatus includes a submount having a mounting surface and a top surface opposite the mounting surface. A slider has a bonding feature that interfaces with the mounting surface of the submount, and two or more layers are disposed between the mounting surface of the submount and the bonding feature. The two or more layers are configured to enhance light absorption of light in proximity to the bonding feature. The light originates from a source of electromagnetic energy that illuminates the top surface of the submount.

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.
