Abstract:

Analytical and numerical modeling of tensor characteristics of nonlinear optical activity for layered-periodic crystal structures superlattices is carried out. Calculations are executed in frames of the long wavelength approximation for electromagnetic field at neglecting of the harmonics generation and effect of the probe wave on the effective medium optical characteristics. The relations determining nonlinear optical activity, electrogyration effective tensors for the structures from bianisotropic layers are derived. The detailed analysis is made for the superlattices formed by cubic crystals of GaAs-type. Domains of parameters values at which the effective nonlinear gyrotropy characteristics exceed ones for the monocrystal components of the superlattices are ascertained.
