Abstract

Abstract Translated from French Pour réaliser des opérations logiques sur des signaux optiques binaires (E, C, H, M), le procédé consiste à utiliser un amplificateur optique non linéaire (1) muni d'un port avant et d'un port arrière recevant respectivement une onde avant (M) et une onde arrière (Pe) modulée. L'onde (S) sortant par le port arrière est séparée de l'onde arrière (Pe) en exploitant l'opposition de leurs sens de propagation. Application à la commutation ou à la transmission de données optiques. <IMAGE> To perform logical operations on binary optical signals (E, C, H, M), the method consists in using a non-linear optical amplifier (1) provided with a front port and a rear port receiving respectively a front wave (M) and a modulated rear wave (Pe). The wave (S) exiting through the rear port is separated from the rear wave (Pe) by exploiting the opposition of their directions of propagation. Application to switching or transmission of optical data. <IMAGE>
