Abstract :
The combinatorial frequency generation by the quasi-periodic Fibonacci and Thue -Morse stacks of magnetically biased semiconductor layers, illuminated by pump waves of two tones, has been analysed in the self-consistent problem formulation, taking into account the nonlinear dynamics of charges. It is demonstrated that the external magnetic bias significantly enhances the nonlinear interactions in the stacks. The effects of the layer sequence and parameters on the properties of the combinatorial frequency waves emitted from the stacks of magnetised semiconductor layers are discussed.
