Effect of α-factor on the dynamics of a bilayer semiconductor structure

A system consisting of two thin films interacting resonantly with a light field is considered. The model formulated for such a system is based on the approximation of two-level atoms and takes into account the peculiarities of the semiconductor medium, in particular, the effect of the ratio of dispersions of real and imaginary parts of the susceptibility (α-factor). It is shown that the inclusion of the α-factor leads to an additional nonlinearity and a considerable modification of the set of steady states of the system. The effect of α-factor on the dynamic regimes emerging in the system is discussed.
