The successful fabrication of miniature optical components is key for progressing current optical technologies. A family of such miniature optical components must be able to efficiently rotate linearly polarized light at small scales. Estefanio Kesto, under the guidance of Dr. Miguel Levy, is studying the interaction between light and ferromagnetic iron garnet nanostructures. It has been observed that the polarization rotation of linearly polarized light, known as the magneto-optic response, traveling through such a nanostructure will be enhanced. The ferromagnetic iron garnet nanostructures pictured above, which enhance the magneto-optic response, are being studied to further miniaturize polarization rotators and other interferometric components. Additionally, Professor Levy and his research group are diving into the unexplored region of magneto-optic beam splitting and its applications in classical and quantum computing.
