Magneto-optical Kerr effect in a dielectric film with cubic optical nonlinearity on a magneto-electric slab

Abstract

We investigate magneto-optic Kerr effect at light reflection from a nonlinear optical dielectric film on a bigyrotropic magneto-electric slab. We analyzed the optical nonlinearity and the magneto-electric coupling contributions to the Kerr rotation angles for both s- and p-polarized light at the incidence angles close to pseudo-Brewster angles.
