Abstract
The present disclosure relates to magnetization-free Faraday rotator systems, apparatuses, and related methods. One such system comprises a Faraday rotator device comprising a magneto-optical composite material having first and second magnetic component materials in a periodic or uniform pattern in an X-Y plane, wherein the first and second magnetic component materials are magnetized along a Z-axis in opposite directions and the Faraday rotator device produces nonzero magnetic Faraday rotation for the electromagnetic wave propagating in a Z-axis direction in the absence of an external bias magnetic field.
