Gaël Mouret (LPCA-ULCO) has more than 20 years of experience in the field of THz and related techniques. He has had more than 50 articles published in high quality journals, and 15 invited international conferences (on place l’ORCID). Since 2000, G. Mouret has developed several THz spectrometers and has boosted the development of a unique THz synthesiser based on a photomixing technique. Also, G. Mouret has supervised the project concerning the ultra high-resolution frequency analysis of the Coherent Synchrotron Radiation which resulted in publication in “Nature Communication” showing clearly its discrete nature in which a specific heterodyne detection has been implemented [Tammaro2015]. Thus, G. Mouret has cultivated strong skills in latest developments in THz domain, in optoelectronic conversions and in frequency metrology using frequency combs. He has been the coordinator of the several major projects since 2000 (ACI, Programme REI de la DGA, ANR).
