Patent ID: 7343060

Claim:
A light transmission and reception module comprising: a belt-shaped macromolecular optical waveguide film having an optical waveguide, the waveguide film having a first end and a second end, an optical transmitter having a light emitting element and a first sub-mount for holding the light emitting element, a portion of the first sub-mount forming a notch for mounting the first end of the macromolecular optical waveguide film on the first sub-mount so that a light emitted from the light emitting element may be coupled to an incident end surface of the optical waveguide, and an optical receiver having a light detecting element and a second sub-mount for holding the light detecting element, a portion of the second sub-mount forming a notch for mounting the second end of the macromolecular optical waveguide film on the second sub-mount so that the light emitted from an exit end surface of the optical waveguide may be received in the light detecting element, wherein the light emitting element and light detecting element are fixed on the first and the second sub-mounts, respectively, by using a resin that is the same as a resin composing a core of the optical waveguide.
