SPP 2314 - MLL-based Integrated THz Frequency Synthesizers (MINTS)
In the project MINTS it is planned to investigate and demonstrate electronic-photonic THz frequency synthesizer architectures which conform to the requirements of integration in silicon photonics (SiPh) and/or Indium Phosphite (InP) photonic technology. Building on the excellent spectral properties of mode-locked lasers (MLL) it is the target to ...

FOR 5208 - Modelling and simulation of the coupled acoustic, electrical, and thermal dynamics of piezoceramics
The determination of material parameters of piezoceramics for actuator applications by means of an inverse method requires an efficient method for the simulation of the different physical processes in the piezoceramic sample. In addition to the electrostatic equations and acoustic wave propagation, this project focuses on the causal description of ...

FOR 2863 - Scalable THz Transceiver Impairment Model
Compared to radios operating at purely optical wavelengths or RF/microwave frequencies, the combination of extremely high absolute bandwidths and high relative bandwidths in the THz frequency regime, paired with the severe performance limitations of technologies operating in the so-called "THz-gap", imposes unique challenges on modern digital ...

3D-Rekonstruktion des Paderquellgebietes im Jahr 1920
Die Pader ist ein Kultur- und Naturerbe von europ?ischer Bedeutung. Und das schon seit rund 1.200 Jahren. Die Stadt bewirbt sich deshalb mit ihrem Stadtfluss um das Europ?ische Kulturerbesiegel (EKS). Im Rahmen dieser Bewerbung haben der Verein ?Freunde der Pader“, ein Historikerteam der Universit?t und das Stadtmuseum Paderborn das westliche ...

TRR 142 - Ultrafast coherent opto-electronic control of a photonic quantum system (B06*)
In this project we will integrate semiconductor quantum dots in field-tunable microcavity heterostructures to achieve ultrafast coherent opto-electronic control of the emitter cavity coupling. By tuning different quantum dot transitions in and out of the cavity resonance we aim to generate (i) cavity assisted two-photon emission, (ii) hyper ...

TRR 142 - Subcycle nonlinearities of ultrastrong light-matter coupling (B08*)
In this project we will investigate subcycle nonlinearities of highly narrowband THz cavity polaritons in the deep-strong light-matter coupling regime. Cyclotron and intersubband resonances of n-type modulation-doped GaAs/AlxGa1-xAs multi quantum wells fabricated by molecular beam epitaxy will be coupled to a novel generation of THz metal ...

TRR 142 - Nonlinear strong-field dynamics of atomically thin transition metal dichalcogenides (A10)
Monolayers of Transition Metal Dichalcogenides (TMDCs) exhibit very high exciton binding energies of several hundred meV and extraordinarily strong optical nonlinearities. Stacking several monolayers allows one to tailor these properties by the choice of materials and their relative orientation. We will explore and manipulate such samples by using ...

Nachhaltigkeitsoptimiertes Life Cycle Assessment technologisch hochkomplexer Produkte am Beispiel Automobilbeleuchtung
In the NALYSES project, a sustainability-optimized life cycle of highly complex technological products is to be realized. Already in the development process, reparability and reusability after the product's end of life (through material recovery and reuse of entire assemblies) are to be taken into account, which requires the development of novel ...
