The project targets the development of integrated ultrafast light sources and their proof-of-concept application as trigger for deterministic single and entangled-photon emitters based on semiconductor quantum dot. Given their compact size, these quantum light sources are scalable for industrial fabrication, but in the current demonstrations they triggered with large and expensive laser systems. Our goal is to replace the complex trigger lasers with fast and stable semiconductor laser oscillators which fit on a small semiconductor chip which allows scaling together with the rest of the quantum photonic system following the roadmap of quantum photonic integration, while also ensuring state-of-the-art quantum light source performance. The research is carried in collaboration with the leading European and US-based research groups in the field of development and quantum technology applications of semiconductor single and entangled-photon sources.
