在本論文中描述一種新型的塑膠透鏡光纖成型技術，其優點是製造快速、可一次大量製作，並且增加耦合率。此塑膠透鏡光纖的製作方式是先利用文獻所使用的點膠方式在平頭光纖頭端點膠，膠體會因為表面張力自然形成球面透鏡，之後再利用高電壓產生靜電吸引的方式將球面透鏡拉伸成錐狀後固化而成錐狀透鏡。利用點膠的方式製作透鏡有一些限制，包括點膠量控制、固化收縮率及透鏡形狀等。因此在本論文中，將改善點膠製作透鏡的限制，使點膠製作透鏡的方式能製作更高耦合率透鏡。

A novel method to form plastic lensed fiber that could be used to manufacture in bulk quickly and raise the coupling efficiency is proposed. The way to form plastic lensed fiber is droping the mucilage on the fiber endface which is described in the reference, then the mucilage will be formed ball lens with surface tension. Next step is to force the ball lens to hyperbola shape with electric force.
The method contains some restrictions including controlling the volume of the drop, the shrinking rate after curing, and the shape of the fabricated lens. The way improving the restriction of fabrication to achieve high coupling efficiency is described in this paper.
