文摘
A quarter-wave plate combined with a mirror realizes a pure rotator on the reflected beam, hence it realizes the same polarization transformation of a Porro prism, which has been recently demonstrated as a universal compensator for the non-reciprocal circular birefringence present in a retracing path. In the present work, the mirrored quarter-wave plate has been experimentally proved to effectively compensate for the non-reciprocal circular birefringence introduced by a variable Faraday rotator.
