| dc.description.abstract | 本論文中，我們提出利用彎曲波導耦合表面電漿於金屬微米半環上，透
過改變微米金屬環與彎曲波導的相對位置，獲得能夠在金屬微米環上增強
表面電漿共振的結構，並使用使用限時域差分法 (Finite-Difference Time-
Domain Method, FDTD)來模擬實際電磁波於波導內傳播及耦合到金屬環上
產生表面電漿共振模態的行為。
本論文藉由改變波導使用的材料，將傳統稜鏡耦合使用的折射率為1.5
的玻璃提升到具有較高折射率為1.7 的波導，而此結構可利用鍺(Ge)氧化物
來實現，這樣的改進使光場能更好的局限於波導內，使更多能量能夠耦合到
金屬環上並增強表面電漿耦合，使該結構具對環境變化具有較高靈敏度，使
用光偵測器結合本元件可將靈敏度提高至10-10RIU。 | zh_TW |
| dc.description.abstract | In this thesis, we launched a light in TM mode into a curved waveguide to generate surface plasmon polariton on a metallic micro-ring made by gold in Otto configuration. By changing the location of metallic micro-ring to curved waveguide, we can enhance the strength of the surface plasmon resonance. The structure is analyzed by the Finite-Difference Time-Domain Method. The refractive index of the curved waveguide is changed from 1.5 to 1.7. The confinement ability of the waveguide is improved. The energy coupled on metallic micro-ring is used to excite the surface plasmon polariton. The device shows a better sensitivity 10-10RIU. | en_US |
