An FNRS-qualified researcher at the OPERA laboratory, Ecole Polytechnique de Bruxelles, François Leo has been working for many years on an innovative optical source, optical frequency combs. This revolutionary optical source won its inventors the Nobel Prize in Physics in 2005. It has since been shown that the use of two coupled sources can greatly speed up spectroscopic and metrological measurements.

The project, HIGHRES, stands for High resolution dual comb spectroscopy and ranging. In this European project, François Leo is proposing a new technique that should make it possible to improve by a factor of a thousand the resolution currently obtained with this dual comb technology. Following a theoretical analysis, François Leo will construct innovative frequency combs using optical fibres. Finally, he will experimentally demonstrate two applications of this new technique, which is essential for applications such as gas detection and large-scale metrology.

This project has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant  agreement No GA101125625).
