  • Waveguide having plasmonic strips for heat-assisted magnetic recording
    Patent number: 11443764
    Abstract: An apparatus includes a slider configured for heat-assisted magnetic recording. The slider includes an input coupler configured to receive light excited by a light source. The slider includes a waveguide core tapering along a light propagation direction from a first cross-sectional width to a second cross-sectional width, the waveguide configured to provide a surface plasmon-enhanced near-field radiation pattern proximate an output end in response to the received light. One or more cladding layers surround the waveguide core. At least one strip of plasmonic material is disposed between the waveguide core and at least one of the one or more cladding layers.
