레이저를 이용한 광섬유 곡률 형상 제어 및 초정밀 클리빙 기술

Abstract

In this study, beam divergence through an optical fiber has been controlled through shaping of the optical fiber tip using a CO2 laser, which make the beam divergence smaller than the conventional diamond wheel cleaving method. Precise length cleaving of an optical fiber inserted in a ferrule using a femtosecond laser has also been investigated with respect to changes of the laser pulse energy. A ribbon fiber composed of 12 optical fibers could be cut precisely at different lengths in a micrometer scale
