Abstract:
A method for manufacturing a polymer optical waveguide comprising at least a cladding layer of a first polymer, and a core portion of a second polymer formed in a recessed portion provided on a surface of the cladding layer of the first polymer, the method comprising the steps of:coating the first polymer in molten state or in solution to a molding plate having a projected shape in cross section for forming the core portion; curing the first polymer by ultraviolet rays or by heat; and stripping the cured first polymer from the molding plate, thereby obtaining the cladding layer having the recessed portion transferred to the surface thereof from the molding plate, wherein the molding plate and the polymer are exposed to an atmosphere of liquid or vapor when the first polymer or the second polymer is stripped from the molding plate.
