The rise of applications such as autonomous cars, human-machine interaction, AR/VR and the rise of AI have provided a strong demand for ever more accurate and smaller CMOS image sensors both in the IR and in the visible range. For this next generation of IR imagers, the strong requirement for high performance coupled to even more aggressive miniaturization are mainly limited by pixel optics. High-quality color and IR spectrum acquisition cannot be performed today using the same cell, (...)

Development of metasurfaces for the optical detection of chiral molecules
19 avril, par adminRHThis PhD thesis topic will focus on the theoretical, numerical, and experimental development
of metasurfaces for the optical detection of chiral molecules. To achieve this, we aim to max-imize the chirality of the electromagnetic field at nanoscale volumes close to the metasur-face. Optical detection of enantiomers is motivated by numerous applications, but studies
have mostly focused on the development of chiral nanostructures inducing strong circular
dichroism. In this thesis (...) -

Ultrafast nonlinear optical response and dynamics of 2D thin films
22 septembre 2023, par adminRHDescription : Two-dimensional thin films are well-known for their high optical nonlinearities. For this reason, they are currently the best candidates for mode-locking of laser systems.1 Recently, during two PhD thesis, we optimized Sb2Te3 and Bi2Se3 layers to obtain significant nonlinear absorption. More specifically, the saturable absorption behavior obtained was the highest ever reported in the field of nonlinear optics by similar experimental techniques.2-5. These high optical (...)

Mesure microondes d’analogues de poussières protostellaires pour améliorer la compréhension de la formation des planètes
7 mars 2023Contexte : Cette thèse s’effectuera dans le cadre du projet interdisciplinaire Dust2Planets dont le but est d’étudier les premières étapes de la formation planétaire, en particulier la croissance des poussières dans les disques protoplanétaires. Nous étudions les signatures de la croissance des poussières dans les disques proto-planétaires à travers une approche innovante, la mesure en microonde des propriétés optiques d’analogues de poussières. En effet, les processus exacts de croissance (...)
