Abstract

This talk discusses a concept to study nonlinear optics through controllable nonlinearities in semiconductor superlattices. A predictive microscopic Nonequilibrium Green's Functions approach is used to deliver input to a relaxation-rate approximation approach leading to analytical expressions for the nonlinear polarization at arbitrary orders. These results open the possibility of extending the whole field of nonlinear optics to the GHz-THz range and the potential to design materials and devices for a large number of applications, including spectroscopy of biomolecules, which typically have strong GHz-THz resonances.
