Abstract :
The variation in transmittance of an MFR-FPC was suppressed to less than 0.03 dB by controlling the application direction of a magnetic field with a magnitude exceeding the saturation field of the Faraday elements. The MFR-FPC can high perform high-speed polarization control at greater than 40 turns/s on a Poincare sphere and high-reproducibility polarization control because it has no mechanical parts.
