Abstract (en)
[origin: WO2007012730A2] The invention concerns a device for receiving (100) an optical signal comprising at least one pulsed optical signal ?<SUB>0</SUB> 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 ?<SUB>0</SUB>, 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.
