The subject of research is the calculation of the absorption coefficient and changes of the refraction index as well as the contributions of the linear and nonlinear effects to optical properties of the structure. Methods are self-consistent solution of Schr?dinger and Poisson equations to obtain the energy spectrum of the structure. Results are new scientific knowledge about the influence of the degree of an ionization of the impurity delta-layer to optical properties delta-doped QWs. Scientific novelty is the possibility of the adjustment of the optical characteristics of QWs by the ionization of the impurity delta-layer inside the QW. Application is THz modulator on the base of delta-doped QWs.
