ABSTRACT
We have investigated the temperature dependence of χ[sup (3)] optical nonlinearities associated with mobile carriers in a superlattice. Our computer calculations show that at temperatures near 300 K, the population of higher minibands can significantly increase Χ[sup (3)] over that predicted by considering only the lowest miniband. The magnitude of this increase is strongly correlated with the layer configuration of the superlattice and its associated band structure.
