Method, transmitter, receiver, and system for communicating information carried by a polarization divided optical signal in an optical fiber, comprising: producing and transmitting a polarization divided optical signal OTApol comprising optical sideband pairs SBLA, SBHA each having one sideband SBLA at a first polarization and an other sideband SBHA at a second polarization that is orthogonal to the first polarization, the one sideband and the other sideband carry the same set of information A; and receiving and detecting the polarization divided optical signal OTApol to produce an electrical signal RFApol corresponding to the polarization divided optical signal; down converting the electrical signal to produce, for each sideband pair, a first converted signal BBLA corresponding to the one sideband SBLA and a second converted signal BBHA corresponding to the other sideband SBHA; and extracting the set of information A for each sideband pair using a polarization diversity scheme. |

1. A method for communicating information carried by a polarization divided optical signal in an optical fiber comprising:
producing and transmitting a polarization divided optical signal (OTApol; OTAB1pol; OTAB2pol; OTAB3pol) comprising optical sideband-pairs (SBLA, SBHA; SBLA, SBHA, SBLB, SBHB; SBLA2, SBHA2, SBLB2, SBHB2; SBLA2, SBHA2, SBLB3, SBHB3) each having one sideband (SBLA; SBLA, SBLB; SBLA2, SBLB2; SBLA2, SBLB3) at a first polarization and an other sideband (SBHA; SBHA, SBHB; SBHA2, SBHB2; SBHA2, SBHB3) at a second polarization that is orthogonal to the first polarization, and where the one sideband and the other sideband carry the same set of Information (A; A, B); receiving and detecting the polarization divided optical signal (OTApol; OTAB1pol; OTAB2pol; OTAB3pol) so as to produce an electrical signal (RFApol; RFAB1pol; RFAB2pol; RFAB3pol) corresponding to the polarization divided optical signal; down converting the electrical signal so as to produce, for each sideband pair, a first converted signal (BBLA; BBLA, BBLB; BBLA2, BBLB2; BBLA2, BBLB3) corresponding to the one sideband (SBLA; SBLA, SBLB; SBLA2, SBLB2; SBLA2, SBLA3) and a second converted signal (BBHA; BBHA, BBHB; BBHA2, BBHB2; BBHA2, BBHB3) corresponding to the other sideband (SBHA; SBHA, SBHB; SBHA2, SBHB2; SBHA2, SBHA3); and extracting the set of information (A; A, B) for each sideband pair using a polarization diversity scheme operating on the first converted signal and the second converted signal of each sideband pair. |
