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 ...

TRR 142 - Three-photon state generation with on-chip pump suppression in topological waveguides (A09*)
In this project, we experimentally and theoretically study a degenerate four-wave mixing source for the generation of three-photon states, where the photons are generated inside the topological mode and propagate away from the interaction region. The design using topological protected surface modes intrinsically provides a strong suppression of the ...

TRR 142 - Generation and characterization of quantum light in nonlinear systems: A theoretical analysis (C10*)
We develop novel approaches based on integro-differential equations and quantum-channel descriptions for the tailored generation of nonclassical light and its propagation in structured media. By devising a multilinear process matrix formalism and accounting for complex dispersion in photonic crystals, we characterize quantum properties of light. ...

TRR 142 - Polaron signatures in the optical response of lithium niobate (B07*)
This joint theory-experiment project will explore the rich physics of polarons and their optical signatures. In particular, we plan to resolve their influence on the linear and nonlinear optical properties of the material as well as their condensation, hopping and dissociation characteristics in interaction with intrinsic and extrinsic point ...

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 ...
