The optical fiber comprises an inner core (refractive index: n1) including the optical central axis, an outer core (refractive index: n2) encircling the inner core, and a cladding (refractive index: n3) encircling the outer core. The relationship between the refractive indexes is expressed as n1>n2>n3. The inner core is made of practically pure silica glass undoped with GeO2. The outer core and the cladding are doped with a refractive-index-reducing dopant such as fluorine. An optical transmission line and an optical communications system are structured by using the foregoing optical fiber.

Abstract: The present invention provides fabrication methods of a polarization-maintaining optical waveguide, which forms a polarization-maintaining structure in an optical waveguide (including an optical fiber) easily. The method forms one or more stress-applying parts in a cladding of an optical waveguide utilizing density change induced in the cladding by implanting ions accelerated with high acceleration energy into the cladding. If necessary, changing the acceleration energy of the ion beam, using masks, rotating the optical waveguide against the ion beam, implanting ions from various directions, and/or using various kinds of ions are preferable.
