Light in Complex Nanostructures

The Light in Complex Nanostructures (acronym COS) group studies the properties of coherent systems involving multiple and strong scattering of light with individual or ensemble of quantum or classical nano-objects or both. We tackle the problem starting from the elementary level (individual nanoresonators), to the microsystem level (nanoresonators possibly dressed by quantum emitters, small nanoresonator assemblies), towards the mesoscopic scale (metasurfaces).



The group would be delighted to successfully support the application of a young researcher for a junior (Chargé de Recherche) CNRS position in January 2024. 

The group received significant grants in 2023 and is presently offering several postdoc positions:

  • Within the interdisciplinary ERC project UNSEEN (2.2 M€), we study nanostructured surfaces that offer new visual effects. We will understand how to design the structures to control their far field appearance attributes, such as specular and diffuse colors, glossiness, transparency, iridescence… We offer several postdocs positions on electromagnetic model of disordered systems, appearance characterization, color harnessing, rendering, fabrication with top-down and bottom-up approaches. More details on the topic can be found in Nature Mater. 21, 1035–41 (2022) and ACS Nano 17, 6362–72 (2023). Talented PhD students are also welcome.
  • In collaboration with ST-Microelectronics (Grenoble), we are actively engaged in the advancement of numerical electromagnetic techniques and software for simulating the diffraction arising from large optical metasurfaces with >10000 metaatoms. We offer a 3-year postdoc position  for this exciting project driven by tangible applications within our dynamic academic setting. The postdoctoral researcher will have the opportunity to validate the numerical simulations by comparing them with real experimental data collected by our partners at ST-Edinburgh, with part-time involvement expected at their facilities. See JOSA A 37,70-83 (2020) and Comput. Phys. Commun. 284, 108627 (2023).
  • For the ANR project WHEEL on Non-Hermitian physics and quasinormal modes, we are offering a 2-year postdoc position on a topic of the properties of light in time-varying nanoresonators. See our recent reviews on the topic: Normalization, orthogonality, and completeness of quasinormal modes of open systems: the case of electromagnetism in 2022, Nanoscale Light Confinement: the Q’s and V’s in 2021.
