Abstract

An optical waveguide film that can supply power at extremely low cost, and a light transmission and reception module using this film are provided. A macromolecular optical waveguide film is composed of a square-shaped waveguide core which extends in a film length direction, a conductive wires which extends in the film length direction and is arranged in parallel with the waveguide core, and a cladding which surrounds the waveguide core and the conductive wire. The two conductive wires are provided, and the waveguide core is provided between the two conductive wires.

Claims

1. An optical waveguide film, comprising:

a waveguide core that extends in a film length direction and guides light as waveguide light;

a conductor for power supply that extends in the film length direction and is provided in parallel with the waveguide core; and

a cladding that surrounds the waveguide core and the conductor.

2. The optical waveguide film of claim 1, wherein the conductor is provided so as to be held between a pair of position regulating members.

3. The optical waveguide film of claim 1, wherein two conductors are provided, and the waveguide core is provided between the two conductors.

4. The optical waveguide film of claim 1, wherein the conductor contains at least one selected from copper, iron, nickel, gold, aluminum and alloys of these metals.

5. The optical waveguide film of claim 1, wherein the conductor is provided by applying conductive paste.

6. The optical waveguide film of claim 1, wherein the conductor is a conductive wire.
