碩士 === 國立中央大學 === 照明與顯示科技研究所 === 104 === In this thesis, we study the surface plasmon polariton effect on a metallic micro-ring to generate a nano-magnetic field. The structure consists of a metallic micro-ring and InGaAs pulley-type waveguide on GaAs substrate. COMSOL Multiphysics is used to analyze the device. Positive charges are positioned on the metallic micro-ring. The surface plasmon polariton is induced on the surface of metallic micro-ring by launching the light into the InGaAs waveguide. The propagation of the surface plasmon polariton along the direction of the incident light drives the charge flow to form an electric current on the metallic micro-ring. According to Biot-Savart law, it can form a nano-magnetic field in the center region of the metallic micro-ring.
