Comparison of phenomenological models with a microscopic theory for semiconductor optical nonlinearities
I. Rumyantsev, N. H. Kwong, Ryu Takayama +1 more
A microscopic theory of the third order coherent semiconductor optical response is used for the investigation of four-wave mixing signals. The theory is based on the dynamics-controlled truncation formalism and evaluated for the case of resonant excitation of heavy-hole excitons. This approach allows for a direct comparison with other theories (microscopic or phenomenological). and yields a detailed understanding of important many-body effects such as excitation-induced dephasing.
