本研究提出了D型光纖的研磨方法，並結合光柵製作濾波元件。實驗中，首先將多模光纖研軸向的一侧進行研磨，直到被研磨的一侧已達光纖纖芯。D型光纖研磨完成後，利用光學全像干涉微影技術結合黃光微影技術，使用Ultra123正光阻製作光柵元件在光纖纖芯上。在實驗中我們能精準的控制光纖的研磨深度；研磨後之光纖的傳輸損耗低於0.1dB。而布拉格表面光柵的深度和週期，可利用精密的旋轉台調整角度，進而控制光柵的深度與週期，並以原子力顯微鏡(AFM)測量其結果。實驗最後，使用近場量測之end-fire coupling量測技術，以光頻譜分析儀(OSA)分析並探討濾波器之光學傳輸特性。

In this thesis, we proposed a novel optical fiber filter using a D-shaped optical fiber. Firstly, a multimode optical fiber was side polished to the core surface to form a D-shaped fiber. Secondly, a photoresist was used to form a surface Bragg grating on the core surface in terms of the holographic technology. The experiments showed that the side-polished depth of the fiber can be accurately controlled. The loss of the D-shaped fiber is less than 0.1dB, measured using loss meters. In addition, the depth and the period of the surface Bragg grating can be easily controlled in terms of an accurate rotating stage. The period and depth of the grating were measured in using of AFM technology. Finally, the transmission characteristics of the filter were measured in terms of Optical Spectral Analyzer (OSA).
