Title (EN) OPTICAL FIBER WITH LENS
(FR) FIBRE OPTIQUE COMPORTANT UNE LENTILLE
Abstract:
(EN) An optical fiber (20) having a lens formed on the end surface of the fiber for enhancing the photocoupling to a light beam. A lens (26) which has a wedge shape composed of two inclined parts (24) symmetrical with respect to the axis (Ac) of a core (22) and a flat part (25) perpendicular to the axis of the core is provided on the tip of an optical fiber (21).
(FR) Fibre optique (20) dont la surface d'extrémité comporte une lentille servant à amplifier le photocouplage à un faisceau lumineux. La pointe d'une fibre optique (21) comporte une lentille (26) présentant une forme de coin composée de deux parties inclinées (24) symétriques par rapport à l'axe (Ac) d'un noyau (22) et d'une partie plate (25) perpendiculaire à l'axe du noyau.
