摘要

本論文利用薄膜光學的概念來設計製作新式的SPR薄膜感測器，來調變表面電漿共振感測器之吸收波長波段。利用介電質膜與金膜所製作而成的SPR光纖感測器，與傳統單層金膜SPR光纖感測器，透過熔接動作製作出雙共振區域的SPR光纖感測器。原本在600 nm-700 nm波段的表面電漿共振感測器之吸收波長，分別依照TiO2不同膜厚與ITO做比較，將其調變至1000-1100 nm、1100-1300 nm、1300-1500 nm、1500-1600 nm，再將兩者熔接形成一條光纖，分析SPR光纖感測器之靈敏度及山梨酸甲濃度測量。

The concept make of the multi-layer SPR fiber sensor for modulating the absorption in wavelength. Both the SPR fiber sensors, with a dielectric thin film (TiO2 or ITO films) coated on the gold film and the traditional single-layer gold film SPR fiber, through the splicing operation exhibit double-resonance calleys in the SPR resonance measurement. Both the original in the 600-700 nm absorption band of surface plasmon resonance sensor with the gold film deposition only and TiO2 or ITO film deposited on the gold film surface in 1000 nm-1100 nm, 1100 nm-1300 nm, 1300nm-1500 nm, and 1500 nm-1600 nm absorption band surface plamon resonance sensor, have been carried out for the comparison of the potassium sorbate solutions with different concentrations. The traditional gold-deposited SPR sensor and the new gold/dielectric deposited multi-layer sensor were implemented for investigatory surface resonances in the different wavelength ranges of 600 nm to 700 nm, and 1000nm to 1600 nm respectively.
