| Summary: | 碩士 === 國立中山大學 === 機械與機電工程學系研究所 === 97 === For the requirements of high-speed signal transmission has been increasing, the fiber array in the communication system has a lot of advantages which can not be replaced. But the loss of coupling efficiency is a difficult problem as the distance of communication is getting longer and longer. In order to increase the transmission and the coupling efficiency, we produce the two with high precision to reach the goal.
The technique producing one dimension fiber array is very adept now. This paper chooses mounting several one dimension fiber array to produce the two dimension fiber array. Because BGA has self-alignment character, the fiber array can get nice mounting accuracy in horizontal but can’t get in vertical. We use active packing to manufacture two dimension fiber. In this process we exert external force to control the mounting height. In the first, use approximate software to get the best manufacturing parameter. Then complete the experiment and compare the result with the approximation.
