| contents | Optical memory effects are well-known types of amplitude-domain wave correlation enabling control over light scattered through diffusive materials or multimode fibers. In this letter, we report the phenomenon of random polarization memory effect. We observe that, despite strong scattering, which leads to random spatial polarization distributions at the multimode fiber output, local polarization states of the optical field maintain a high degree of correlation with respect to the input polarization state. This newly observed effect reveals an additional layer of deterministic behavior in light propagation through multimode fibers and opens up new opportunities for imaging and sensing. |
