Abstract

An expression was obtained from which one can determine the law of plasma waves ω(k) in a two-dimensional semiconductor superlattice under the influence of a nonlinear electromagnetic wave. In the extreme case of weak nonlinearity, an analytical expression for ω(k) is found. The possibility of controlling the frequency of the plasma wave by varying the parameters of a nonlinear wave was established.
