    • Post-doc: Ultrafast Laser Structuring for Optical Metasurfaces

      Start: September-November 2025

      Duration: 1 year

      Location: Laboratoire Hubert Curien, Université Jean Monnet (UJM), St-Etienne, France

      Application deadline : July 1st, 2025.

      Main objective: Develop and implement a novel self-adaptive ultrafast laser surface structuring methodology for creating multispectral metamaterials with low detectability across visible and infrared wavelengths. This involves the design, fabrication, in-situ characterization, and optimization of hierarchical surface structures on metallic substrates.

Master internship openings

    • Internship - Vanadium Dioxide-Based Films for Randomizing Photonic Emission and Absorption of Integrated Circuits

      Period: March to August 2024

      Application deadline: 15th December 2023

      Location: Laboratoire Hubert Curien (Université Jean Monnet - UJM, St-Etienne)

      The goal is to develop a smart coating that will prevent exploiting the photonic emission and absorption from integrated circuits, effectively limiting the use of optical techniques to reverse-engineer microchips or access the stored secret data.

      Interested candidates should send a CV to both:
