  • Polarization scrambling based on cascaded optical polarization devices having modulated optical retardation
    Patent number: 8780433
    Abstract: Techniques and devices use cascaded optical polarization devices having modulated optical retardation to control optical polarization of light and can be configured for polarization scrambling. Uniform rate scrambling and quasi-uniform rate scrambling modes are provided in described devices and rate-additive designs based on multiple cascaded devices are also disclosed to achieve high-speed scrambling.
    Type: Grant
