Abstract

Directional couplers of gradient-index plastic optical fibers were fabricated and characterized. In particular, we have employed a core-facet technique to make the directional couplers, which require mechanical side polishing and linkage. We have measured insertion loss, excess loss, and coupling ratio of the fabricated couplers as a function of polishing depth and coupling length. We found that polishing depth of <TEX>$\~300{\mu}m$</TEX> and coupling length of <TEX>$\~35mm$</TEX> are optimum conditions for minimizing the insertion and excess losses and for achieving 1: 1 coupling ratio.
