摘要： A mixture of a urethane monomer and a urethane oligomer having a group represented in Fig. 4 and a polymerization initiator, which is a precursor of an elastomer exhibiting a flexural modulus of elasticity of 1,000 MPa or less after curing, is used as a clad material. The clad material is applied on a base plate and is pressed from above by a stamper and is spread into a thin film. After the clad material is cured to form an under clad layer, a core is formed on the under clad layer. Then, the above clad material is applied on the under clad layer, is pressed by a stamper from above and is spread into a thin film. The latter clad material is cured to form an upper clad layer. Finally, the base plate is removed, and a film optical waveguide capable of being bent with a small radius of curvature is obtained.

摘要： A mixture of urethane monomer and urethane oligomer containing the group shown in Fig. 4, and polymerization initiator, or a precursor of an elastomer having the flexural modulus after curing of smaller than or equal to 1,000 MPa is used as the clad material. The clad material is applied on the substrate and is pressed by the stamper from above to thinly spread the clad material. The clad material is then cured to form the lower clad layer, and thereafter, a core is formed on the lower clad layer. Subsequently, the clad material is applied on the lower clad layer and is pressed by the stamper from above to thinly spread the clad material, which clad material is then cured to form the upper clad layer. Finally, the substrates are removed to obtain a film waveguide that can be bent at a small curvature radius.
