Optical Transmission System and Device for Receiving an Optical Signal

The invention concerns a device (100) for receiving an optical signal comprising at least one optical signal of angular frequency omega0 modulated by an electrical signal of angular frequency Omega whose phase phi1 varies according to the value of at least data bit to be transmitted. The reception d...

More Information
Summary:The invention concerns a device (100) for receiving an optical signal comprising at least one optical signal of angular frequency omega0 modulated by an electrical signal of angular frequency Omega whose phase phi1 varies according to the value of at least data bit to be transmitted. The reception device (100) comprises a polarisation separator (105) for separating the modulated optical signal of angular frequency omega0, into first and second optical signals of different polarisation, means (140, 102, 103, 104) of obtaining two electrical signals, means (110a) of modulating the first optical signal from the first electrical signal, means (110b) of modulating the second optical signal from the second electrical signal, and means (115) of combining the first modulated optical signal and the second modulated optical signal in order to form a recombined optical signal.
