Abstract: Magnetic Faraday rotation is widely used in optics and MW. In uniformmagneto-optical materials, this effect is very weak. One way to enhance it isto incorporate the magnetic material into a high-Q optical resonator. Oneproblem with magneto-optical resonators is that along with Faraday rotation,the absorption and linear birefringence can also increase dramatically,compromising the device performance. Another problem is strong ellipticity ofthe output light. We discuss how the above problems can be addressed in thecases of optical microcavities and a slow wave resonators. We show that a slowwave resonator has a fundamental advantage when it comes to Faraday rotationenhancement in lossy magnetic materials.
