摘要
Various plasmonic elements with waveguide trapping are provided. In one embodiment, a plasmonic element includes a waveguide layer including a first surface through which incident light enters the waveguide layer. The waveguide layer includes a medium and an array of plasmonic structures disposed within the medium. The medium has dielectric properties. The resonant frequency of the plasmonic structures is responsive to the dielectric properties of the medium. The plasmonic element is configured to trap incident light scattered by the plasmonic structures in a waveguide mode.
