Abstract

La présente invention concerne un dispositif mélangeur utilisable dans les systèmes de communication optique. Le dispositif mélangeur de l'invention est remarquable en ce qu'il est constitué par un tube en matériau transparent d'indice n1, terminé par deux faces planes et perpendiculaires à l'axe et dont les parois sont en contact avec des milieux d'indice n2 et n3. La lumière fournie par tout faisceau conique arrivant en P, l'angle du cône étant compris dans l'angle d'acceptance du mélangeur, est régulièrement répartie sur la face F' de sortie si la longueur L est supérieure à L'invention est du domaine des communications optiques.
