POLARIZATION SCRAMBLING BASED ON CASCADED OPTICAL POLARIZATION DEVICES HAVING MODULATED OPTICAL RETARDATION

摘要

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.
