摘要： A mask having a center hole for passing through a center fiber, which is one of multiple fibers, and multiple surrounding holes for passing through surrounding fibers, which are the remainder of the multiple fibers, and a stress adjusting unit for holding stresses generated in the center fiber and surrounding fibers to a desired constant value, respectively, are installed. The surrounding fibers are rotated around the center fiber by rotating the mask. The center fiber and the surrounding fibers that have been twisted around the center fiber are heated with a heating apparatus and drawn. The center fiber and the surrounding fibers are fixed using a clamp installed between the stress adjusting unit and the heating apparatus.

摘要： The object of the present invention is to provide a wide-band optical fiber coupler whose light-branching ratio is independent of the wavelength of light rays to be transmitted therethrough as well as a method for preparing the wide-band optical fiber coupler. When an optical fiber 1 having zero-dispersion at 1.55 .mu.m band and an optical fiber 2 having zero-dispersion at 1.3 .mu.m band are fused and drawn to form a coupled portion 3, a light beam 15 is incident upon the optical fiber 2 and the intensity of the light beam outgoing through either of these optical fibers 2 or 1 is measured to detect the light-branching ratio observed at the coupled portion 3. The drawing operation is interrupted at an instance when the detected light-branching ratio falls within the range of 50.+-.5%.

摘要： A rare earth element-doped multiple-core optical fiber has an outer cladding layer and a plurality of cores each covered with a primary cladding layer. The cores are positioned substantially on a central axis of the outer cladding layer and separated with a predetermined spacing S from each other by the primary cladding layer. The outer cladding layers are made of SiO.sub.2, or SiO.sub.2 added with a dopant like F, Ge, etc. The primary cladding layer is made of SiO.sub.2 doped with Er, or SiO.sub.2 doped with Er and F together and formed to have a predetermined thickness of 1.0 .mu.m.about.1.5 .mu.m to form the predetermined spacing S. The Soot glass rods for cores and primary cladding layers are immersed in an Er-compound solution, then picked up, dried and consolidated to form Er--Al co-doped SiO.sub.2 --GeO.sub.2 transparent glass rods. The glass rods are inserted into a quartz tube and collapsed by heat to fabricate an optical fiber preform rod, then heated to be drawn to provide an Er-doped multiple-core optical fiber.
