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 - Compact high performance photon pair source using ultrafast hybrid modulators based on CMOS and LNOI (C11*)
The project aims to study and demonstrate miniaturized sources of decorrelated photon pairs with high repetition rate. The goal will be achieved by jointly integrating high-bandwidth electro-optic modulators, and a specifically tailored parametric down-conversion (PDC) section, both in a lithium-niobate-on-insulator (LNOI) platform. To obtain ...

TRR 142 - Hybrid lithium niobate on insulator quantum photonic integrated circuit (C08*)
In this project, we will explore thin-film lithium niobate on insulator (LNOI) as the material platform for quantum photonic integrated circuits. After transfer printing of cavity coupled InAs quantum dots onto a LNOI circuit, we will on-chip frequency convert the on-demand generated photons from the quantum dot using a periodically poled LNOI ...
