Modification of the linear and nonlinear polarization dynamics in semiconductors owing to the Kerr magneto-optic effect

Abstract

The contribution to polarization dynamics from a combination of linear birefringence, anisotropic nonlinear refraction, and a longitudinal magneto-optic effect is discussed. A Hamiltonian formalism is developed using Stokes parameters. It is found that by periodic reversal of the magnetic field, avenues are opened up to exploit Faraday rotation, for example, as an optical isolator, and polarization switching in an integrated optical environment. A practical implementation is discussed that uses semiconductors and a shaped-surface conductor.
