Abstract
A bidirectional optical transmission and reception module includes a substrate having one surface provided with waveguides and mirrors for deflecting radiation into the substrate and on an opposite surface of the substrate is provided a laser diode serving as a transmitter, a photodiode as a receiver, and a terminal for an optical fiber, each opposite the mirrors on the waveguides. Optical connections between the optical fiber and the laser diode and between the optical fiber and the photodiode are carried out through the substrate and via the waveguides. An optical coupler is also provided between the waveguides.
