Abstract
Optical bistability in superlattice structures on a nonlinear substrate is studied theoretically using an attenuated total-reflection configuration. It is shown that even up to Λ/λ ≅ 0.2 (where Λ is the period of the superlattice and λ is the radiation wavelength) the superlattice structure and its equivalent (in the long-wavelength limit) anisotropic layer have almost identical nonlinear behavior although the linear properties may differ significantly.
