PLASMONIC OPTICAL WAVEGUIDE USING PLASMONIC COUPLING BETWEEN NANO-APERTURE AND NANO-PARTICLE

摘要

The present invention relates to a plasmonic optical waveguide using plasmonic coupling between a nano-aperture and a nano-particle. The plasmonic optical waveguide includes the nano-aperture formed with an opening of a nano-scale through which light enters; and a single metal nano-particle arranged at the focal point of the nano-aperture to generate plasmon coupling in association with the light output from the nano-aperture. The plasmonic optical waveguide has an effect of forming a small and strong high-intensity high-density light spot of a sub-wavelength size, in which an amplification rate is increased at the output surface of the nano-particle more than a few hundred times compared with the incident light, since the light is transmitted by plasmon coupling generated between the nano-aperture and the nano-particle.

1. A plasmonic optical waveguide comprising:
a nano-aperture formed with an opening of a nano-scale on one side to pass light; and a metal nano-particle positioned on the one side on which the opening is formed and positioned at or near a focal point of the nano-aperture to generate plasmon coupling by interacting with the nano-aperture.
