Missions

Have you ever been fascinated by the shimmering colors of fish scales or butterfly wings? These stunning structural colors arise not from pigments, but from nanostructured surfaces that manipulate light in remarkable ways. What makes them truly captivating is not just the color, but the overall appearance—a subtle and complex visual effect that bridges science, art, and design.
Thanks to recent advances in nanotechnology, it is now possible to fabricate large-scale artificial nanostructures using high-refractive-index materials like metals and semiconductors. Unlike natural nanostructures, these artificial surfaces offer new degrees of freedom and the potential to create entirely novel visual effects.

Activités

-This is the exciting challenge at the heart of the ERC UNSEEN project (€2.2M), launched in late 2023 at the Laboratoire Photonique Numérique et Nanosciences (LP2N) in Bordeaux. The project brings together expertise in optical metasurfaces, disordered media, and computer graphics.

Compétences

Candidate profile:
PhD in optics, nanophotonics, or a related field, defended within the last two years.
Strong interest in light scattering, disordered systems, and/or computer graphics rendering. Creativity and curiosity to explore new scientific ideas.

Contexte de travail

We are seeking a creative and motivated postdoctoral researcher to join our interdisciplinary team. This position offers:
Hands-on experience with cutting-edge optical metasurfaces, both ordered and disordered.
Opportunities to model and exploit light scattering in complex media for real applications.
A chance to explore novel ways to manipulate light and fully exploit the many degrees of freedom offered by these metasurfaces.
Collaboration with a team at the interface of nanophotonics, optics, and digital rendering, fostering broad scientific and technical skills.
More information about the research group is available on Philippe Lalanne's Google Scholar page. The topic of disordered metasurfaces is presented in the review article: Lalanne et al., Advances in Optics and Photonics 17, 45-112 (2025). Recent original works from the group can be found in: Chen et al., Nano Letters 25, 13221 (2025) and Chen et al., arXiv:2505.02244 (2025). Join us in exploring unseen optical worlds and help shape the future of nanophotonic design!
