Paper Abstract

The absorption of a weak electromagnetic wave by free electrons in semiconductor superlattices in the presence of a laser radiation (non-modulated and modulated) is discussed. The electron - acoustic phonon scattering is assume to be dominant. The analytic expression of the absorption coefficient is obtained. The dependence of the absorption coefficient on the temperature, the frequency and the superlattice parameters is analyzed. The dependence of the absorption coefficient on the time for the case of modulated laser radiation could allow to rise the deep penetration of laser radiation in superlattices.
