HOE 89/F 178 Abstract of the disclosure Method and apparatus for producing a star coupler from polymer optical waveguides Mechanically robust star couplers of polymer optical waveguides having low insertion losses and small fluctua- tions between the individual output fibers are obtained if polymer optical waveguides are arranged in parallel in the middle region of an apparatus and fused with one another under pressure and with the supply of heat. The optical cladding of the polymer optical waveguides has been previously removed. The method is easy and cost- effective. The apparatus is composed of a lower part with a channel recessed therein and an upper part with a male die located therein, which male die corresponds in its shape to the shape of the channel.
