Abstract: PROBLEM TO BE SOLVED: To provide a material for optical waveguide having high polymerizability and excellent solvent resistance, and to provide an optical waveguide utilizing it and a method for manufacturing it. SOLUTION: Materials for optical waveguide constituting organic material layers 11a, 12a are activated and converted into a cladding part 11 and a core part 12 respectively when the materials are irradiated with energy beam. The materials for an optical waveguide contain an oxetane compound, an oxirane compound and a cation polymerization initiator. Because the oxetane compound has an oxetane ring, it has an excellent repetitive reactivity in a chain reaction. Thereby the materials exhibit high polymerizability in a chain reaction so as to produce polymers with large mechanical strength and excellent solvent resistance. Refractive indices of the core part 12 and the cladding parts 11, 13 are controlled because an oxetane compound and an oxirane compound are excellently compatible with each other and refractive indices of respective compounds are reflected in the refractive index of a hardened mixture.

Abstract: PROBLEM TO BE SOLVED: To provide a method for the production of an optical waveguide by which an optical waveguide having a light-reflecting mirror at a prescribed inclination angle with respect to the propagation direction of light can be easily formed with good reproducibility, and to provide a method for the production of an optical transmitting and receiving device. SOLUTION: A photomask 25 with a light-shielding film 24 is positioned on a photosetting resin layer 12'. The light-shielding film 24 has openings 24b and inclined faces 24b. The region of the inclined face 24b acts as a gray scale region, which transmits light in the quantity according to the thickness of the light-shielding film 24 which changes gradually. Then by irradiating the mask with light L1, in the region directly under the inclined faces 24b, the light reaches the resin layer 12' while the quantity of the transmitted light is controlled according to the thickness of the light-shielding film 24. Therefore, when the non-hardened part of the resin layer 12' is dissolved and removed, light- reflecting mirrors are formed on both ends of the optical waveguide cores, with the mirrors consisting of inclined faces which make an almost 45 angle with the surface of the transparent substrate 11.

Abstract: PROBLEM TO BE SOLVED: To provide the optical waveguide device and optical transmission and reception device which enables two-way communication by propagating light signals bidirectionally by using an optical waveguide formed on a substrate and their manufacture. SOLUTION: In an optical waveguide 15 at least nearby its one end side (side A), a grooved cut part 31a having border surfaces 16a and 17a is provided crossing a light propagation direction. Received signal which is propagated in the optical waveguide 15 from the other end side (side B) is reflected internally by the border surface 16a and exits from the flank of the optical waveguide 15. Transmitted light which is made incident on the end surface 18a on the side A of the optical waveguide 15 is transmitted through the border surface 17a and made incident on the border surface 16a. Even the optical waveguide formed on the substrate is able to send and receive light signals in two directions and the density of optical wiring can be made high.
