Abstract
Official abstract text for this publication.
A method of manufacturing an optical fiber assembly into which optical fibers are integrated includes: preparing an alignment member having through holes with a pitch that is greater than a coating diameter of the optical fibers; inserting each of the optical fibers into one of the through holes; after the inserting of the optical fibers into the through holes, holding the optical fibers on both sides of the alignment member by a pair of grippers; after the inserting of the optical fibers into the through holes, connecting at least adjacent ones of the optical fibers by disposing an adhesive material on at least one side of the alignment member; and forming an optical fiber assembly by curing the adhesive material in a state in which the optical fibers held by the grippers are stretched along an optical axis.

1 . A method of manufacturing an optical fiber assembly into which optical fibers are integrated, the method comprising: preparing an alignment member having through holes with a pitch that is greater than a coating diameter of the optical fibers; inserting each of the optical fibers into one of the through holes; after the inserting of the optical fibers into the through holes, holding the optical fibers on both sides of the alignment member by a pair of grippers; after the inserting of the optical fibers into the through holes, connecting at least adjacent ones of the optical fibers by disposing an adhesive material on at least one side of the alignment member; and forming an optical fiber assembly by curing the adhesive material in a state in which the optical fibers held by the grippers are stretched along an optical axis. 2 . The method of manufacturing an optical fiber assembly according to claim 1 , wherein the holding of the optical fibers comprises: disposing the alignment member near a first gripper of the pair of grippers; holding the optical fibers by the first gripper after disposing the alignment member; and after holding the optical fibers by the first gripper, moving the alignment member from a vicinity of the first gripper toward a second gripper of the pair of grippers. 3 . The method of manufacturing an optical fiber assembly according to claim 1 , wherein the adhesive material is a UV curable resin, and the curing of the adhesive material comprises applying an ultraviolet ray to the adhesive material. 4 . The method of manufacturing an optical fiber assembly according to claim 2 , wherein the adhesive material is a UV curable resin, and the curing of the adhesive material comprises applying an ultraviolet ray to the adhesive material.
