  • Frequency modulation coherent optical communications system with continuous polarization scrambling
    Patent number: 5329394
    Abstract: A coherent optical communications system with continuous polarization scrambling, wherein such scrambling is obtained by combining orthogonally polarized radiations at different frequencies emitted by two independent sources. The two sources may be employed to build the transmitted or the local oscillator of the system.
