The aim is the calculation of the energy spectrum, obtaining values of linear and nonlinear optical coefficients. Method - theoretically calculated. Theoretical and practical results - the dependence of the linear and nonlinear coefficients for the optical absorption and relative refractive index change associated with intersubband transitions of electrons in the conduction band on the spatial parameters of the structure is analyzed. Novelty - GaAs/AlGaAs structures within parabolic band and effective mass approximations and 2-dimensional problem using diagonalization method are calculated. The effectiveness of implementation - the possibility of creating an optical modulator based on the properties of the considered structures.
