  • Surface plasmon enhanced optical devices for integrated photonics
    Patent number: 8849072
    Abstract: An optical device for integrated photonic applications includes a substrate, a dielectric waveguide and a surface plasmon waveguide. The dielectric waveguide includes a dielectric waveguide core disposed relative to a dielectric waveguide cladding and a common cladding. The surface plasmon waveguide includes a surface plasmon waveguide core disposed relative to the common cladding and a surface plasmon waveguide cladding. The common cladding couples the dielectric waveguide and the surface plasmon waveguide.
    Type: Grant
