Abstract
The present invention provides a hybrid coupling structure of a short range surface plasmon polariton and a conventional dielectric waveguide, including a dielectric substrate layer, a dielectric waveguide layer positioned on the said dielectric substrate layer, a coupling matching layer positioned on the said dielectric waveguide layer and a short range surface plasmon waveguide portion, formed on the said coupling matching layer, for conducting the short range surface plasmon polariton. The present invention also provides a coupling structure of a long range surface plasmon polariton and a dielectric waveguide, including a dielectric substrate layer, a dielectric waveguide layer, a coupling matching layer and a long range surface plasmon waveguide portion upward from below respectively.
