Abstract: The disclosed methods enable the production of plasmonic near-field transducers that are useful in heat-assisted magnetic recording. The plasmonic near-field transducers have an enlarged region and a peg region. The peg region includes a peg region in proximity to an air-bearing surface above a recording medium and also includes a flared region between and in contact with the enlarged region and the peg region. The flared region can act as a heat sink and can lower the thermal resistance of the peg portion of the near-field transducer, thus reducing its temperature.

Abstract: A waveguide a core extending along a light propagation and a coupling layer adjacent one side of the core along the light propagation direction. A gradient index material is adjacent to at least one side of the coupling layer. The gradient index material has a first refractive index proximate the coupling layer and a second refractive index away from the coupling layer. The gradient index material is configured to direct light from an input facet to the core layer.

Abstract: A mounting surface of a read/write head is prepared to receive an epitaxial layer. The mounting surface is proximate a waveguide of the read/write head, and the waveguide is configured to receive an optical output from the epitaxial layer. The epitaxial layer is transfer printed on to the mounting surface. The mounting surface maintains a vertical alignment between the optical output and the waveguide. The epitaxial layer is processed to form a laser integrated with the read/write head.
