Abstract
A coupling element is composed of a thick core fiber having an end formed by a first and second end surface with the first end surface extending substantially perpendicular to the axis of the fiber and the second end surface, which has a highly reflective mirror layer being inclined to the first end surface and to the axis. A second fiber, which is thinner than the first fiber, is coupled by a butt-joint to the first end surface and a third fiber which is also a thick core fiber branches off obliquely from the side of the first fiber adjacent the end.
