ABSTRACT:
A wavelength multiplexing device comprising a switching matrix (18) of the N to 1 type, which has several successive stages (18a,18b) of controllable optical couplers (20) interconnected to form a tree structure and modulating means (24) connected to the output of the switching matrix (18). The device further has N sources (10,12,14,16) each emitting a continuous light beam having a particular wavelength to an input of the matrix, and a control circuit (22) connected to the couplers and controlling the latter so as to select P wavelengths from among the N available wavelengths. The device allows efficient transmission of data through an optical network.
