Abstract
The embodiments disclose a stack feature of a stack configured to confine optical fields within and to a patterned plasmonic underlayer in the stack configured to guide light from a light source to regulate optical coupling.
Claims20
An apparatus comprising
- a substrate;
- a continuous layer over the substrate comprising
- a first heat sink layer;
- and
- a plurality of patterned features over the continuous layer comprising
- a second heat sink layer,
- a plasmonic underlayer over the second heat sink layer, and
- a magnetic layer over the plasmonic underlayer,
- wherein the position of the plasmonic underlayer in the plurality of patterned features confines patterned feature-applied heat without substantial loss of the heat to other patterned features through lateral thermal bloom.
