© 2021, Allerton Press, Inc.Abstract: Nonlinear optical processes are considered, including the generation of the third harmonic and the rotation of the polarization vector of a wave, which depends on the intensity of light in media whose properties are due to the non-zero Berry curvature. The associated gyrotropy results in a dependence of the phase velocity on the polarization of the radiation, which violates the condition phase matching for one of the polarization components of the interacting waves.
