Abstract
A metal waveguide is coupled to a dielectric waveguide to obtain transmission of light in a plasmon mode along an edge of the metal waveguide. Efficient, broadband light transmission is obtained, achieving a low insertion loss, using standard processing tools. An efficient integrated optical circuit is obtained.
Claims25
An optical circuit comprising:
- a metal waveguide;
- and
- a dielectric waveguide coupled to the metal waveguide,
- wherein light from the dielectric waveguide is adapted to be guided in a plasmon mode substantially external to the metal waveguide and confined substantially adjacent an edge of the metal waveguide.

An optical coupling arrangement comprising:
- a first dielectric waveguide;
- a metal waveguide optically coupled to the first dielectric waveguide;
- and
- a second dielectric waveguide optically coupled to the metal waveguide, wherein light from the first dielectric waveguide to the second dielectric waveguide is adapted to be guided in a plasmon mode substantially external to the metal waveguide and confined substantially adjacent an edge of the metal waveguide.
