Our digital world is growing at great speed implying the constant need for improving the network quality, broadening band widths allowing fast data traffic. This calls for materials with excellent properties such as the ferroelectrics studied in this research proposal exhibiting the possibility to encode signals via electrooptical modulation or generation of coherent tunable light sources through optical nonlinear processes.

The introduction of accessible wet chemical deposition routes for textured growth of oxide based ferroelectrics such as Sr_xCa_yBa_1-x-yNb₂O₆ in Si-technology will allow a thorough screening of the electro-optic and nonlinear properties of these materials. The project aims at pushing the material properties even more by spatial engineering the domain orientation of the textured thin film. Smart design of crystal orientation in micro- or even nanometer scale will expand the application field even further.
