Method of and a device for coupling optical fibers and opto-electronic components

In the fiber and in any fiber (F), a reflecting surface (F1) is created that is generically tilted with respect to the main propagation path (T1) of the optical radiation in said fiber, so as to originate by reflection an additional propagation path (T2) that is generically deflected with respect to said main propagation path (T1). In a mounting support (2) common to the fiber (F) and the related opto-electronic component (O), a groove is made along an external face (2a) so as to accomodate the optical fiber (F) in a tight condition. The groove (3) is then covered through a laminar cover, that is transparent to the radiation and has a flat surface (4a).The fiber (F) is inserted into said groove in order that said deflected propagation path (T2) passes through said cover (4) of material transparent to the radiation, and the opto-electronic component (O) is mounted on said cover (4) in alignment with said deflected propagation path (T2).
