Mathieu Jeannin joined C2N as a CNRS research fellow in October 2022. After a PhD in Grenoble in the joint team Institut Néel (CNRS) - INAC (CEA) - Université Grenoble Alpes on the coupling between semiconductor nanostructures and plasmonic antennas, he carried out a post-doctorate at the MPQ laboratory, then at the LPENS in Paris, driven by his taste for nanofabrication and the desire to discover new physics, based on intersubband transitions. There, Mathieu developed new devices operating at THz frequencies based on three-dimensional metallic metamaterials. He then joined C2N in 2020, to study photodetectors operating in the strong light-matter coupling regime in the mid-infrared spectral range.
At C2N, his research project focuses on the exploitation of optical and/or electronic non-linearities in the strong light-matter coupling regime to propose innovative optoelectronic devices in the mid-infrared. This project will be developed in the ODIN team of the Photonics department.
