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 (12)

1. A light transmission and reception module, comprising:

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,

a light transmitting section that has a light emitting element and a sub-mount for holding the light emitting element, and holds one end of the optical waveguide film onto the sub-mount so that light emitted from the light emitting element is coupled with an incident end surface of the optical waveguide; and

a light detecting section that has a light detecting element and a sub-mount for holding the light detecting element, and holds the other end of the optical waveguide film onto the sub-mount so that light emitted from an emission end surface of the optical waveguide is detected by the light detecting element.

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

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

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

5. The light transmission and reception module of claim 1 , wherein the conductor of the optical waveguide film is provided by applying conductive paste.

6. The light transmission and reception module of claim 1 , wherein the conductor of the optical waveguide film is a conductive wire.
