I obtained my MSc in Optics and Photonics from Imperial College and my Engineering degree from Supélec. I obtained my PhD in nanophysics in 2016, in the joint team Nanophysics and Semiconductors between Institut Néel (CNRS) and INAC (CEA) in Grenoble. I studied the optical emission properties of II-VI semiconductor quantum dots embedded inside nanowires, and the opportunity to control these properties using plasmonic nanoantennas. For this work, I was awarded the Nanoscience Foundation Thesis Prize in 2017.
I then joined the Laboratoire Matériaux et Phénomènes Quantiques (MPQ) in 2017, and the Laboratoire de Physique de l’École Normale Supérieure (LPENS) in 2019 funded by a post-doctoral allocation I obtained from the DIM SIRTEQ. My work focused on developing a novel three-dimensional, metallic metamaterial architecture allowing to dramatically enhance the optoelectronic response of intersubband transitions in doped GaAs quantum wells resonating at THz frequencies. I demonstrated the ultra-strong coupling between the electron gas and the meta-atoms, funneling incident radiation into an ultra-subwavelength volume of 10-6λ3. Using this architecture I demonstrated THz QWIP detectors operating up to 60 K, setting the path towards THz photodetectors operating at liquid nitrogen temperature.
Since 2020, I have been a postdoc researcher in the Centre Nanosciences et Nanotechnologies (C2N). My main focus is the demonstration of novel mid-infrared optoelectronic devices operating in the strong coupling regime between light and matter. In particular, I study quantum cascade detectors (QCDs) operating in the strong coupling regime to advance towards a description of electronic transport in polaritonic systems. I am also studying intersubband saturation in polaritonic devices: I recently proposed a unified description of saturation and bistability of intersubband transitions in the weak and strong light-matter coupling regimes, opening the way towards mid-infrared saturable absorbers.
