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 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.
