Abstract
A polymer optical waveguide includes a lower cladding layer of a polymer resin which has a recess and projection transferred from a mold provided with a recess and projection for forming a core portion of the optical waveguide by applying a polymer in molten state or in solution on the mold, and curing the polymer by ultraviolet rays or by heat, and stripping the cured polymer from the mold in a liquid. The cured polymer can be easily stripped from the mold, which allows the mass manufacturing of polymer optical waveguides having various film thicknesses.
