OPTICAL FIBER COUPLING MEMBER AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2014/034726

A1

Provided is a multi-core fiber coupling member that reduces a decrease in coupling efficiency when a multi-core fiber and a fiber bundle are coupled, as well as a method for producing same. A coupling member has an end on one side in contact with a first optical waveguide formed with a single bundle of a plurality of cores, the bundle being covered with a clad, an end on the other side in contact with a second optical waveguide composed of a plurality of cores each of which is covered with a clad, and a predetermined medium filled between the ends. Respective mode field diameters of light beams caused to enter from the optical paths of the first optical waveguide are changed. Further, intervals of the light beams, whose mode field diameters have been changed, are changed, and the light beams are guided to the cores of the second optical waveguide, respectively.
