Optical Fiber Terminal Structure, Optical Element Connection Structure, and Method for Manufacturing Optical Fiber Terminal Structure

摘要

An optical fiber terminal structure is comprised of a plurality of optical fibers, a plurality of high-Δ optical fibers connected to the optical fibers, respectively, and a capillary. The capillary has a hole in which the optical fibers and the high-Δ optical fibers are inserted, and the optical fibers and the high-Δ optical fibers together are fixed in the hole. Connection parts of each of the optical fibers and the high-Δ optical fibers are also positioned inside the capillary, and end surfaces of the high-Δ optical fibers are exposed so that adjacent high-Δ optical fibers are in contact with each other in an end surface of the capillary.
