An optical waveguide includes a linear metallic thin film having a light delivering unit coupled to one end thereof, through which light is incident; and at least more than two dielectric layers surrounding the metallic thin film. In the optical waveguide, an effective refractive index and a propagation loss in the metallic thin film is reduced so that long-range light transmission is realized. Further, a loss of light caused by the coupling to optical fiber, which is coupled to one end of the metallic thin film, is simultaneously reduced.

Optical waveguide

An optical waveguide for transmitting a surface plasmon-polariton wave includes a metallic thin film formed to have a triangle-shaped cross-section; and a pair of first and second dielectric layers coupled to each other such that the opposing surfaces thereof come in contact with each other, with the metallic thin film interposed therebetween, the first and second dielectric layers having a different refractive index and a positive or negative dielectric constant.
