An optoelectronic module, intended to provide a conversion of an electrical signal from an electronic board into an optical signal propagated in free space or vice versa, includes the following stack: an electronic board, intended to act as an interface with an electronic application board; an electronic control component suitable for controlling an optoelectronic component, the electronic component being attached directly onto the electronic board and electrically connected to the electronic circuit; an optoelectronic component suitable for transmitting or receiving a light signal via its upper surface, the optoelectronic component being attached directly on the top of the electronic control component and electrically connected to the electronic component; an optical device suitable for transmitting an optical signal; an optical device support, the support being attached, preferably by gluing or brazing, directly onto the electronic board so as to ensure the mechanical alignment between the optical device and the optoelectronic component.

The field of the invention is that of fiber-optic communication devices known as transceivers, used in the aeronautical field for ensuring that on-board electronic computers can converse with one another, or in civil telecommunication. The subject of the invention is a single-channel transceiver comprising essentially a transmitting optoelectronic part, a receiving optoelectronic part, and a specific optical configuration for transmitting and receiving optical signals on a single optical port in real time and using the same wavelength. The optical architectures according to the invention include no semireflecting components, thus making it possible to reduce light energy losses at transmission and reception of the optical signals. These transceivers are particularly well suited for the construction of single-fiber full-duplex optical communication networks allowing simultaneous transmission and reception of signals.
