Abstract
The invention concerns bidirectional optical fiber connections, and more particularly an optical coupling device between an emitting electroluminescent diode and a detecting photodiode, the optoelectronic component according to the invention comprising an electroluminescent diode called DEL sealed in a box of the transistor box type the cover of which carries a microlens centered on the optical axis of the box, while inside the box are integrated: a photodiode mounted at the side of the DEL and outside the optical axis, a semitransparent mirror and a mirror support, this support being machined so as to form a second mirror that reflects light to be detected towards the detecting diode; the novel component can be used in bidirectional optical connections, in computers and telephone exchange centers.
