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.
