Abstract

Abstract Translated from French L'invention concerne les liaisons bidirectionnelles par fibre optique : elle concerne plus particulièrement un coupleur optique entre une diode électroluminescente d'émission et une photodiode de détection. The invention relates to bidirectional fiber optic links: it relates more particularly to an optical coupler between a light emitting diode of emission and a detection photodiode. Le composant optoélectronique selon l'invention comprend une diode électroluminescente (2) dite DEL, encapsulée dans un boitier (19+20) de type boitier de transistor, dont le couvercle porte une microlentille (21), sur l'axe optique du boitier. A l'intérieur du boitier sont intégrés : une photodiode - (5), montée à côté de la DEL (2) et en dehors de l'axe optique, un miroir semitransparent (27) et un support (32) de miroir (27), ce support étant usiné de façon à former un second miroir (28) qui réfléchit la lumière à détecter vers la diode de détection (5). The optoelectronic component according to the invention comprises a light-emitting diode (2) called LED, encapsulated in a case (19 + 20) of the transistor case type, the cover of which carries a microlens (21), on the optical axis of the case. Inside the housing are integrated: a photodiode - (5), mounted next to the LED (2) and outside the optical axis, a semi-transparent mirror (27) and a mirror support (32) (27 ), this support being machined so as to form a second mirror (28) which reflects the light to be detected towards the detection diode (5). Application aux liaisons optiques bidirectionnelles, en informatique ou au centraux téléphoniques. Application to bidirectional optical links, in IT or telephone exchanges.
