Abstract

Abstract Translated from French Dispositif de multiplexage en longueur d'onde comprenant une matrice de commutation (18), du type N vers 1, comportant plusieurs étages successifs (18a, 18b) de coupleurs optiques commandables (20) reliés entre eux en une structure arborescente et des moyens de modulation (24) reliés à la sortie de la matrice de commutation (18), N sources (10, 12, 14, 16) émettant chacune un faisceau lumineux continu et de longueur d'onde particulière sur une entrée de la matrice, et un circuit de commande (22) relié aux coupleurs et prévu pour commander ceux-ci de façon à sélectionner P longueurs d'ondes parmi les N longueurs d'ondes disponibles. Wavelength multiplexing device comprising a switching matrix (18), of the N to 1 type, comprising several successive stages (18a, 18b) of controllable optical couplers (20) interconnected in a tree structure and means for modulation (24) connected to the output of the switching matrix (18), N sources (10, 12, 14, 16) each emitting a continuous light beam and of particular wavelength on an input of the matrix, and a control circuit (22) connected to the couplers and designed to control the couplers so as to select P wavelengths from the N available wavelengths. Application à la transmission de données dans un réseau optique. Application to data transmission in an optical network.
