Patent ID: 8849072

Claim:
An optical device for integrated photonic applications, comprising: a substrate; a dielectric waveguide disposed on the substrate, the dielectric waveguide comprising a dielectric waveguide core disposed between a dielectric waveguide cladding and a common cladding; and a surface plasmon waveguide disposed relative to the dielectric waveguide, the surface plasmon waveguide comprising a surface plasmon waveguide core disposed relative to the common cladding and a surface plasmon waveguide cladding, the common cladding configured to couple the dielectric waveguide and the surface plasmon waveguide, wherein optical properties of the dielectric waveguide cladding are different from optical properties of the common cladding; and wherein the effective index of the surface plasmon waveguide is adapted to be non-reciprocal when receiving a magnetic field in a direction transverse to propagation.
