Abstract
Un coupleur réflecteur en étoile destiné à un réseau optique de commutateurs répartis pour les communications radiodiffusées à bande étroite et à bande large comporte une porte (20a) aboutissant dans une surface ou un dispositif réfléchissant (22), un amplificateur de signaux (24) et/ou un filtre disposé dans le chemin entre ladite porte (20a) et ledit dispositif réfléchissant (22) afin de réintroduire la lumière provenant de cette porte dans ledit coupleur à l'état amplifié ou sélectivement selon la longueur d'onde. Le dispositif d'amplification peut être un laser à semi-conducteur ayant un revêtement réfléchissant sur une de ses faces.
