The required accuracy of adjustment in this operation is not very high. Furthermore, the ferrule 25 of an optical waveguide 26 is inserted into the guide sleeve 10. The guide sleeve 10 with ferrule 25 and the adjusting sleeve 8 with basic component 1 are then inserted into a so-called xyz manipulator.

Abstract

Ce dispositif électro-optique comprend un boîtier (16) et un composant électro-optique composite (24) qui contient un composant électro-optique de base (1), notamment une photodiode, une diode laser ou une diode luminescente dans laquelle on peut faire entrer ou dont on peut faire sortir de la lumière. Afin qu'il soit possible de réduire au maximum les coûts de fabrication du boîtier (16) du composant électro-optique de base (1), le composant électro-optique composite (24) comprend une douille de guidage (10) reliée au composant de base (1). On peut insérer cette douille (10) dans un boîtier (16) de réception d'un connecteur(27) d'une fibre optique (26) pourvu d'une ferrule (25) afin d'insérer et guider la ferrule (25). Ainsi, lorsque la ferrule (25) est insérée dans la douille de guidage (10), la fibre optique (26) est optiquement couplée au composant de base (1).
