ABSTRACT:
A coherent optical-fiber transmission system is rendered insensitive to fluctuations of the state of polarization of the electromagnetic field due to propagation along the fiber by varying at the transmitting side the state of polarization of the optical carrier modulated by the information signal to be transmitted. The variation is such that spectral broadening of the intermediate frequency signal at the receiver is kept limited, while reception of half the power outgoing from the fiber is ensured.
