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 - Nonlinear optical surfaces based on ZnO-plasmonic hybrid-nanostructures (C05)
The project targets the efficient manipulation of light beams with simultaneous frequency conversion at an ultrathin metal-zinc oxide metasurface. We plan to manipulate the amplitude and phase of the nonlinear waves based on the structural design and material composition on a nanoscale by utilizing a nonlinear Pancharatnam-Berry phase. By coupling ...

TRR 142; TP C06: Integrierte messungsinduzierte Nichtlinearitäten mit integrierten supraleitenden Detektoren
This project will investigate the theoretical potential and experimental feasibility of integrating superconducting nanowire single-photon detectors (SNSPDs) on lithium niobate waveguides in order to implement a measurement-induced nonlinearity. Such nonlinearities arise from probabilistic mea-surement events and as such, can be implemented at very ...

StudyNow: Eine webbasierte Plattform zur Verstetigung der Lernmotivation von Studierenden mittels Gamification
Das häufig bei Studierenden zu beobachtende Aufschieben von Lernaktivitäten bis kurz vor der Prüfung (Prokrastination) ist für Studierende wie auch Lehrende ein großes Problem. Studierende limitieren durch Prokrastination ihren Lernerfolg und in der Regel auch die daraus resultierende Qualität der Prüfungsleistung. Lehrende wiederum werden durch ...

Galois Groups of Local Function Fields
Computing Galois groups has been a very active topic in the last years. The applicant has made many contributions for the case of Galois group computation over the rationals. Many years ago these computations have been restricted to bounded degree because the algorithms have been dependent on precomputed data. Nowadays, there are implementations ...

Visible Light Sensing
Light-emitting diodes (LEDs) are increasingly being used as a primary light source both indoors and outdoors. In addition to their role as efficient lighting, LEDs also offer potential for new applications in sensor technology like visible light sensing (VLS) thanks to their high switching speed. VLS uses several terahertz (THz) of license-free ...

Blind radar for visual impaired people
The aim of this project is to develop an innovative assistance system for visually impaired people. It uses a 120 GHz FMCW radar that detects obstacles that are outside the range of a conventional cane. To make use as intuitive as possible for users, the radar system is integrated into a handy device. A special lens ensures that only objects within ...

Influence of periodic nanoscale ripple patterns on titanium surfaces on the osteogenic differentiation of human mesenchymal stem cells in combination with chemical and biological surface modifications (NanoTune)
The influence of anisotropic, ordered surface topographies at the low nanometer level on the behavior of human mesenchymal stem cells (hMSC) is thus far insufficiently investigated and poorly understood. Yet topographies with vertical dimensions in the sub-10 nm range and lateral dimensions of the order few 10 nm exhibit high potential to ...
