Abstract

L'invention concerne un dispositif de réception (100) d'un signal optique comprenant au moins un signal optique de pulsation ω0 modulé par un signal électrique de pulsation Ω dont la phase Φl varie en fonction de la valeur d'au moins un bit de données à transmettre. Le dispositif de réception (100) comporte un séparateur de polarisation (105) pour séparer le signal optique de pulsation ω0 modulé, en un premier et un second signaux optiques de polarisation différentes, des moyens d'obtention (140, 102, 103, 104) de deux signaux électriques, des moyens de modulation (110a) du premier signal optique à partir du premier signal électrique, des moyens de modulation (110b) du second signal optique à partir du second signal électrique, des moyens de combinaison (115) du premier signal optique modulé et du second signal optique modulé pour former un signal optique recombiné.
