In this invention, a wave to be modulated (WE) and a command wave (WC) of an optic type are injected simultaneously into the wave guide (4) of a diode (2) that can constitute the semiconductor part of an electroabsorption modulator, the impedance (R) present at the poles of this diode being high enough to allow a modulation in the amplitude of the command wave to be transferred to the wave to be modulated. This invention is particularly applicable to fibre-optic telecommunications systems, particularly for the resynchronization of solitons.

Selon cette invention on injecte simultanément une onde à moduler (WE) et une onde de commande (WC) de nature optique dans le guide d'ondes (4) d'une diode (2) apte à constituer la partie semi-conductrice d'un modulateur à électroabsorption, l'impédance (R) présente aux bornes de cette diode étant suffisamment élevée pour permettre à une modulation d'amplitude de l'onde de commande d'être transférée a l'onde à moduler. Cette invention s'applique notamment dans les systèmes de télécommunications à fibres optiques, notamment pour la resynchronisation de solitons.
