Group Delay Dispersion Measurements on Mid‐Infrared Supermirrors
Advanced Optical Materials, EarlyView.Group delay dispersion of novel semiconductor‐based optics is measured in the mid‐infrared spectral range (2.5 to 4.8 μm$\rm \umu{\rm m}$). Comparisons are made between simulations, measurements conducted with a home‐built white light interferometer, and measurements performed with a commercially available FTIR.

Structural Colors from Ultrathin Lignin Films
Advanced Optical Materials, EarlyView.Thickness‐dependent structural colors in ultrathin lignin films generate a full visible palette, tuned simply by solution concentration and spin speed. Abstract Structural colors offer a sustainable alternative to toxic pigments and dyes, yet their realization from lignin, the most abundant aromatic biopolymer, has remained elusive.

Vertex covering under constraints
, 2019 Cette thèse porte sur le problème de la couverture d'ensembles finis dans une structure discrète. Cette problématique très générale permet de nombreuses approches et nous faisons l'étude de certaines d'entre elles. Le premier chapitre introduit les notions qui seront indispensables à la bonne compréhension de cette thèse et fait un bref état de l'art ...

Sharp Diamond Needles for Single‐Photon Emission
Advanced Photonics Research, EarlyView.We study the morphological evolution of single‐crystal diamond needles oxidized at 650–700 °C. Electron microscopy and photoluminescence reveal temperature‐ and time‐dependent sharpening, length reduction, and surface modifications affecting tip properties.
