Abstract

La présente invention concerne : un substrat d'ancrage de fibre optique (2) qui présente une surface luminescente (21) se trouvant sur la même surface qu'une surface d'extrémité luminescente (1a) d'une fibre optique (1), ainsi que des surfaces de région d'adhésion (22); une lentille de collimateur (4) placée du côté de la surface d'extrémité luminescente (1a) de la fibre optique (1); et un élément de support de lentille (3) qui supporte la lentille de collimateur (4) et maintient la surface d'extrémité luminescente (1a) de la fibre optique (1) et la lentille de collimateur (4) à une certaine distance l'une de l'autre. Ledit élément de support de lentille (3) est fixé par adhésion aux surfaces de région d'adhésion (22), Cette configuration permet d'obtenir un collimateur de guide d'onde optique et un dispositif de commutation optique dans lesquels un élément qui supporte une lentille de collimateur ne se détache pas facilement.
