• A realistic wafer-level integration of metasurfaces with semiconductor lasers (Nature Nanotechnology - 01/2020)

  Ultra-thin flat optical structures, also called metasurfaces, offer an innovative approach to controlling light. By integrating them with vertical emission micro-lasers (VCSELs), they allow the creation of arbitrarily programmable beam networks for imaging and telemetry applications.

• New holography method with GaN metasurfaces (07/2019)

  Conventional hologram designs lack orbital angular momentum selectivity. We designed metasurface holograms consisting of GaN nanopillars with discrete spatial frequency distributions allowing the reconstruction of distinctive orbital angular momentum dependent holographic images. Read more...

• European metrology project GIQS kick-off (06/2019)

  The European project GIQS (Graphene impedance quantum standard) aims at developing impedance standard easier to operate thanks to the use of graphene on SiC. The consortium, gathering 7 national metrology institutes from European network EURAMET and 2 national metrology institutes form Asia has been reinforced by CRHEA and C2N, who will bring their recognized expertise in graphene growth and processing. The project has just started for 3 years.Read more...
