碩士 === 國立中山大學 === 機械與機電工程學系研究所 === 98 === This paper presents a search method of coupling between the laser and fiber , search method to make up through the fiber and the laser inter-position deviation caused optical transmission loss , this search method is applied in the array-alignment is different from the traditional single-alignment , the advantage for the method is simple, through the rough alignment then blind search and angle search , for fiber array find the coupling of the greatest optical power position. In the experiment there are four degrees of freedom to use precise stage to fine-tune the location of fiber array , to reduce losses due to tools to reach precise alignment of purpose ,so we prove our method can achieve the objective of the fiber-optic alignment in our experiments.
