The research area “Materials” is dedicated to new and promising semiconductor nanostructures for nonlinear applications, to material related aspects of the classical nonlinear material LiNbO3, and to the ab-initio theoretical description of photonic materials.
The semiconductor related projects B01 and B02 are concentrated in one part on the growth and analysis of novel ZnO-based nanostructures for multi-photon and harmonic generation (B01) and in a second part on the growth of GaN/Al(Ga)N based intersubband structures and the investigation of their nonlinear and coherent optical properties (B02). Project B03 is focused on the experimental and theoretical analysis of defects and domain walls in LiNbO3. The results and insights from this project are essential for the realization of integrated quantum optical circuits as investigated in pro- jects C01 and C02. Of key importance within this research area is also the central ab-initio theory project B04, which is dedicated to the description and prediction of linear and nonlinear optical pro- perties of both semiconductor and ferroelectric materials and to method development.
