TRR 142 - Tailored KTP and LiNbO3 waveguide structures for counter-propagating parametric down-conversion processes (B05)
This project aims at the fabrication of periodically poled waveguide structures with ultrashort periods in lithium niobate and KTP for counter-propagating parametric down conversion. We will focus on the development of the technological processes required to achieve ultra short domain periods in a combined technological and analytical approach in ...

TRR 142 - Effect of extended and point defects on the ferroelectric and optical properties of LiNbO3 (B03)
The aim of this project is a deeper understanding of the effect of point defects and extended defects on the functional properties of periodically poled waveguide structures. Using a combined approach of theory and experiment, the influence of lattice defects on the optical properties of waveguides (refractive index change, photorefractive index, ...
