ABSTRACT:
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.
