The unprecedented accuracy of modern optical clocks has spurred the development of matching frequency comparison techniques, with optical frequency transfer over fibre emerging as the method of choice. However, international time scales, as well as applications outside metrology, require reliable and economically sustainable time transfer in addition to frequency transfer capabilities. This project will advance fibre-based frequency transfer capabilities in Europe towards a universal tool for time and frequency metrology and beyond.

The project aims at the area of optical fibre based sensors, scintillation materials and systems for the detection of ionizing radiation with optical fibres in critical infrastructures. The research will focus on the detection of ionizing radiation in nuclear reactors and particle accelerators, especially in the presence of an extremely high electromagnetic interference. The proposal is intended for remote monitoring in areas with high radiation in order to increase the operational safety.
