Abstract :
The properties of the three-wave interaction and wave scattering by periodic stacks of nonlinear semiconductor layers with external magnetic bias have been explored, taking into account the nonlinear charge dynamics. It has been shown that the mixing processes in magnetoactive semiconductor structures are enhanced by the magnetic bias and the combinations of layer physical and geometrical parameters. The effects of magnetic bias on nonreciprocity of combinatorial frequency generation are discussed.
