碩士 === 國立虎尾科技大學 === 光電與材料科技研究所 === 102 === In this study, the use of optical holographic interference lithography and photolithography process technology,will produce a Bragg grating formed on the PDMS soft mold, and use technology to produce D-Shaped optical fiber abrasive structure, fixed to the first single mode fiber convex structure on a glass substrate, fixed to the grinding machine after the completion of the polishing. Milling process,grinding process, the use of broadband light source SLD detector with optical power monitoring, and observe the power change,with the pythagorean theorem and optical microscope to speculated that the degree of grinding fiber and the distance from the fiber core, after the completion of the grinding, the Bragg grating with a soft PDMS mold covering the D-shaped optical fiber, capillarity and liquid crystal to flow into the cracks in their. This study successfully developed a D-shaped optical fiber Bragg grating and put on soft PDMS mold, by atomic force microscopy (AFM) to observe the grating depth and period. By tunable laser source and optical circulator measurement and record results, the study and discussion of.
