The microscopic theory for the optical and electronic properties of semiconductors is further developed and applied to model the linear and nonlinear optical properties of metastable semiconductor compounds. Besides analyzing time-resolved pumpprobe and four-wave-mixing spectroscopy the main goal is to provide an adequate theory for the gain and luminescence spectra and laser action in highly excited systems. For this purpose it is necessary to resolve the relevant bandstructure issues, study the carrier transport into the active regions, and address the essential structural properties. The understanding and modeling of the microscopic processes that determine the optical response is a crucial step in order to achieve a controlled way of designing heterostructures with optimal properties. In this project it is planned to closely collaborate with experimentalists who grow, characterize and analyze the metastable semiconductor compound structures. This synergistic combination of theoretical and experimental investigations has been very successful in the past and should enable us to develop and improve also heterostructures based on the new materials.
