Abstract: A polarization rotator rotates a portion of light received from an input surface to an orthogonal polarization. A polarization splitter is coupled to the polarization rotator and includes a channel waveguide section that transmits the rotated portion of the light towards an output surface. The splitter also includes a splitter waveguide separated from the channel waveguide section by a dielectric gap. The splitter waveguide couples an unrotated portion of the light away from a target region of the output surface.

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.

Abstract: A near-field transducer includes a substrate that defines a substrate-parallel plane. The near-field transducer also includes a composite layer deposited on the substrate-parallel plane. The composite layer has a first layer of the plasmonic material and a second layer of an insertion material adjacent the substrate. The insertion material reduces plastic deformation of the near-field transducer at elevated temperatures.
