The evolution of polarization and spin angular momentum (SAM) in periodically rocking superlattices (PRS) is investigated. Unlike in the birefringent crystal, they exhibit unusual properties. The evolution of polarization shows many remarkable trajectories and the SAM oscillates inside the PRS. The results may find applications in polarization-state or optical SAM control.
