Abstract
A method of optical coupling between an optical fiber and an optoelectronic component for an optical-fiber telecommunications link is applied to the fabrication of a transmitting and/or receiving optoelectronic head. In a semiconductor wafer having a p.sup.- layer and a p.sup.+ layer, chemical etching of the p.sup.- layer is followed by n-type doping of an n.sup.+ layer at the bottom of the cavity and on the edge of the cavity. Highly accurate positioning of the optical fiber is thus ensured as well as excellent coupling between the fiber and the light-emitting diode or photodiode thus provided.
