Post-doctoral offer: Optical metasurfaces producing brand-new appearance


Visual appearance is a very common feature of many objects, and is encountered and used in our daily life as a crucial ingredient for determining the desirability or usefulness of objects. The Light in Complex Nanostructures group from the Laboratoire Photonique, Numérique et Nanosciences (LP2N – UMR5298, Institut d’Optique Graduate School, Université de Bordeaux, CNRS) has recently successfully implemented the first tool that predicts the appearance of disordered metasurfaces and has designed several metasurfaces that produce brand-new appearance. The produced images provide much more attributes than earlier studies on metasurface colors, as they include coherent (specular) and incoherent (diffuse) scattering, reflection haze, shading effect, radiosity. We have not yet published any results.


The designed metasurfaces are presently fabricated by our collaborators of an ANR French project (2019-23), using bottom-up and top-down techniques to demonstrate large (unfortunately, polydisperse) and virtually perfect (unfortunately, small) metasurfaces. With this opening position, we engage the caracterisation of the metasurfaces with our new setup and with a new one to be implemented.
