Abstract
An opto-electronic head serving as a connection between a photo-emitter or photo-detector component and a very small diameter optical transmission fibre, designed to facilitate the coupling and adjustment of the respective positions of the optical fibre and the component. To this end, the optical fibre is mounted in a fibre holder incorporating a relatively wide axial passage, except at a constriction point. The passage is flared in frustum-shaped manner on the diode surface side tangential to the fibre bulge maintaining said bulge at an optimum distance from said diode.
