　　在學術界與工業界，消逝場激發之光纖光學元件應用在光通訊系統與平面型光波電路的研究是相當受到矚目的，另外，在國際上主要的研討會上這也一直是熱門的討論議題。而側磨光纖可以用來製作消逝場激發之光纖元件，以目前我們實驗所提出之側磨光纖的製程已經可以成功的製作出先進的側磨光纖，並且進而驗證部分的被動式和主動式之光纖元件。本論文中，我們分別側磨波長為0.633微米和1.5微米的單模態光纖並且以文獻上的理論公式對其做參數上的分析。而我們最終的目標是整合側磨光纖與平面型光波電路之系統。
　　本論文的研究可說是上述長程計劃的初步階段，其目的在於研究薄膜覆蓋式側磨光纖元件中的光傳輸現象。研究過程我們採用幾何光學的理論對光在此種光纖波導的傳輸做一簡易的定性分析，並且與實驗結果做對照，可以發現實驗量測的結果定性上來說符合理論數值計算的預測。這個事實讓我們確信實現整合側磨光纖與平面型光波電路之系統的可能性，此外，在論文中我們也提及了更進一步的研究工作。

　　Evanescent-field fiber-optic devices have been continuous interests in academic and industrial societies. In the applications of optical communication systems. plannar lightwave circuits (PLCs) become hot subjects in key international conferences. In our laboratory, we had fabricated state-of-the-art side-polished fibers and demonstrated some passive plus active evanescent-filed fiber devices. In the thesis, we successfully made side-polished fibers including 0.633μm and 1.5-μm single-mode fibers using the same fabrication processes developed by our predecessors. These fibers were calibrated by the familiar formula. The integratoin of a side-polished fiber and a PLC is the ultimate goal of our research, we did.
　　This was a primitive stage of the long-term research. The purpose of this thesis is to study the light transmissions between a side-polished fiber and a thin film. For simplicity, we deposited a photo resist thin film on the side-polished fiber and adopted a ray-optic analysis to qualitative investigation of the light transmission. From comparisons, we found good agreement between the theoretical calculation and the measurement. The present results show promising in realizing our goal and some further works are included in this thesis.
