碩士 === 國立臺灣大學 === 應用物理所 === 100 === Plasmonics metallic nanostructures can confine and manipulate light down to nanoscale, and give promising scenarios for nanophotonic applications. In this thesis, we have designed and fabricated a new hybrid nanostructure, dielectric-embedded metallic grating, via large patterning nanoimprimt lithog- raphy technique. The plasmonics properties of Fabry-Perot resonance in such device are investigated both experimentally and theoretically. The anticross- ing behavior due to the strong coupling between the surface plasmon polari- tons and Fabry-Perot resonace is observed and explained qualitatively quite well. Our newly designed geometry possesses high electric field enhance- ment, high quality factors and great sensitivity, which will open up a new potential in applications such as integrated plasmonic circuits, bio sensing, atom-trap, etc.
