| 摘要 |
The first and second optical waveguide device portions are optically coupled by 45-degree total reflection mirrors integrally formed in the respective device portions. The light generated by the first optical waveguide device portion is bent upward by the total reflection mirror of the first optical waveguide device portion. The light is totally reflected by the 45-degree total reflection mirror of the second optical waveguide device portion, and coupled to the second optical waveguide device portion. The first optical waveguide device portion has a lens device for focusing the emitted light onto a light emitting portion. The second optical waveguide device portion has a lens device for focusing the incident light onto a light receiving portion.
