    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 apparatus includes a waveguide configured to deliver light to a transducer region. The apparatus also includes a plasmonic transducer that has two metal elements configured as side-by-side plates on a substrate-parallel plane with a gap therebetween. The gap is disposed along the substrate-parallel plane and has an input end disposed proximate the transducer region and an output end. The transducer is configured to provide a surface plasmon-enhanced near-field radiation pattern proximate the output end in response to the light received by the waveguide.
