摘要： A production method of an optical waveguide for a connector is provided, which reduces an optical coupling loss. Cores are formed in a crossing pattern, a branched pattern or a linear pattern, and then an over-cladding layer formation photosensitive resin layer is formed over the cores. In turn, a heat treatment is performed at a temperature of 70° C. to 130° C. to properly form mixed layers in interfaces between the cores and the photosensitive resin layer. By thus forming the mixed layers, the connector optical waveguide can be produced as having a reduced optical coupling loss.

摘要： A method of manufacturing an opto-electric hybrid board which is capable of reducing the number of steps for the manufacture of the opto-electric hybrid board and which achieves the reduction in thickness of the opto-electric hybrid board to be manufactured, and an opto-electric hybrid board obtained thereby. A resist layer is formed on a core-forming resin layer, and is then formed into a predetermined pattern. Resultant portions of the core-forming resin layer serve as cores (optical interconnect lines) 3. Next, a thin metal film 5 is formed on the under cladding layer 2 so as to cover the resist layer and the cores 3. Thereafter, the resist layer is removed together with portions of the thin metal film 5 lying on the surface of the resist layer. Electroplating is performed on the remaining portions of the thin metal film 5 to fill grooves 6 defined between adjacent ones of the cores 3 with electroplated layers 7a obtained by the electroplating. The electroplated layers 7a serve as electrical interconnect lines 7.

摘要： A production method of an optical waveguide that can provide increased production efficiency and can also provide improved workability and production stability and provide an optical waveguide produced by the production method of the optical waveguide. A varnish comprising photopolymerizable resion composition comprising a fluorene derivative and a photoacid generator is coated over an under clad layer 2 and then is dried, to form a resin layer 4 having substantial no surface tack. Sequentially, the resin layer 4 is exposed to light in the state of being contacted with a photo mask 5 by a contact exposure method and then is developed, to form the resin layer 4 into a pattern. Thereafter, the resin layer 4 is cured to form a core layer 3 and then an over clad layer 6 is formed on the under clad layer 2 in such a manner as to cover the core layer 3, to thereby produce an optical waveguide. This method can allow the forming of the resin layer 4 having no surface tack, and as such can allow the use of the contact exposure to expose the resin layer to light. Hence, the number of processes and time-consuming and complicated works involved in the interposition of the spacer can be reduced, thus providing increased production efficiency.

摘要： A plurality of regions for a plurality of optical waveguides are defined on a substrate. Then, optical waveguide under-cladding layers are formed on the respective regions, and dummy under-cladding layers are formed between adjacent ones of the optical waveguide under-cladding layers in a spaced relationship to the optical waveguide under-cladding layers. After cores are formed on the optical waveguide under-cladding layers and the dummy under-cladding layers, an over-cladding layer formation photosensitive resin is applied on the resulting substrate. Subsequently, portions of the resulting photosensitive resin layer for the respective optical waveguides are selectively exposed, and the exposed portions are defined as over-cladding layers. Thus, the optical waveguides are produced as each including the optical waveguide under-cladding layer, the core and the over-cladding layer, and separated from the substrate.
