FOCUS ONTO A NANO-PHOT INDUSTRIAL CLOSE PARTNER:
In-Fine: 10 years of innovation in structural colours applied to visual security and more
Since 2015, the University of Technology of Troyes, via the Light nanomaterials and nanotechnology laboratory, has worked together with the SURYS company( now IN Groupe) through a joint laboratory called In-Fine. The Innovation Center for Industrial Nanostructured Foils aims at developing innovative optical identification devices by combining two industrial and academic complementary knowhows in large scale structuring( roll-to-roll technology) and nanophotonics. Initially supported by the ANR through the starting and consolidation labcom inititatives, the R & D activity based on an initial 8 years roadmap has been organized in 6 research programs such as PLASMOGRAMTM renamed Metasurfaces, Hybrids renamed Multiscale and as for the diversification aspect a sensing and energy oriented program. In 10 years more than 15 R & D projects have been conducted. 15 people have been regularly involved( 8 FTE). NANO-PHOT students are strongly involved, 5 PhD have been conducted together with more than 16 master internships and 2 postdoctotral studies. 3 technologies have been already implemented. These include the PLASMOGRAMTM Reverso technology, the patented ETMF( enhanced Example of an In-Fine studied technology for diffuse transmissive metallic foils) technology and a recently developed techno- al.

and specular reflectance control and tuning( Y. Billet et
logy aiming for specular and diffuse reflectance control( cf. figure below). The take-home message for this successful industrial academic initiative lies in 4 words, meeting, common interest, precise frame of collaboration and confidence. As for the coming five years security and diversification remain the main target with a more global industrial and societal scope that includes the creation of a physical platform for pilot production and collaborative R & D activities with UTT and IN Groupe partners without neglecting the sustainability of the developed process and technologies.
