MiNaO is a joint research laboratory between the CNRS and the ONERA was first created in 2014. It embodies ten years of close collaboration between the Laboratory of Photonics and Nanostructures (LPN) at Marcoussis, now C2N, and the Department of Theoretical and Applied Optics (DOTA) at Palaiseau. The research objectives of MiNaO, ranging from promoting theory to pursuing applications, aim at developing new concepts in metal/dielectric systems structured at the nanometer scale.
