Abstract:
1. A method for producing a bundle structure including a plurality of optical fibers connectable to a multicore fiber having a plurality of cores, the method comprising: inserting a plurality of optical fibers arranged substantially in a close-packed arrangement into a capillary such that distal ends of the plurality of optical fibers stick out from an end surface of the capillary by an identical length; bringing only the distal ends of the plurality of optical fibers into contact with a first adhesive so that the first adhesive is drawn up to a space between the optical fibers and the plurality of optical fibers are tightly attached and bonded together by surface tension of the first adhesive drawn up to the space between the optical fibers; and after the first adhesive is cured, fixing the capillary and the plurality of optical fibers to each other and polishing the end surface of the capillary to obtain the plurality of optical fibers arranged in a close-packed arrangement.
