Beschreibung
Zusammenfassung:	The invention concerns a device for receiving (100) an optical signal comprising at least one pulsed optical signal ?0 modulated by a pulsed electric signal O whereof the $1 phase varies based on the value of at least one data bit to be transmitted. The receiver device (100) comprises a polarizing separator (105) for separating the modulated pulsed optical signal ?0, into first and second optical signals of different polarization, means for obtaining (140, 102, 103, 104) both electric signals, means for modulating (110a) the first optical signal from the first electric signal, means for modulating (110b) the second optical signal from the second electric signal, means for combining (115) the first modulated optical signal and the second modulated optical signal to form a recombined optical signal. L'invention concerne un dispositif de réception (100) d'un signal optique comprenant au moins un signal optique de pulsation ?0 modulé par un signal électrique de pulsation O dont la phase Fl 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 ?0 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.
