Arbitrary polarization control by magnetic field variation
arXiv:2011.07834 · doi:10.1364/AO.404150
Abstract
We propose a universal scheme for the construction of a device for arbitrary to arbitrary polarization transformation, which consists of two quarter-wave plates and two Faraday rotators. Using this device, one can continuously change the retardance and the rotation angle simply by changing the magnetic fields in each Faraday rotator.
