Optoelectronic end piece comprising a fibre optic section of very small diameter and connexion device comprising such an end piece

摘要

The invention relates to an opto-electronic head serving as a connection between a photo-emitter or photo-detector component and an optical transmission fiber of very small diameter. Its purpose is to facilitate the coupling and the adjustment of the respective positions of the optical fiber and of the component. To this end, the optical fiber (2) is mounted in a fiber holder (1) comprising a fairly wide axial duct (23) except at a choke point (22). The conduit (23) flares, on the side of the diode (7). in a frustoconical shape (24) tangent to the bulge (20) of the fiber (2), keeping this bulge (20) at an optimal distance from the diode (7). Application to opto-electronic heads in fiber optic links for medium distance telecommunications.
