Mastering light / matter interactions at scales smaller than the wavelength logo_tutelle 

Energy transfer at the nanoscale,

Photonics is the science and technology of the production of photons, their propagation and their absorption by matter.

The photonic properties of condensed matter depends on the intrinsic properties of its constituents (molecules, crystalline lattice,...) but, as importantly, on their organization at the nanoscale. Thus, nanophotonics addresses the various processes of interactions of light with matter at scales smaller than the wavelength (the wavelength of visible light is between 400 and 700nm ) .

The nanophotonics laboratory focuses on molecular plasmonics, that is the various processes involving photonic interactions between conjugated molecules and metal nanostructures. The design and development of hybrid nano-objects with innovative photonic functions is undertaken by combining the following aspects of nanophotonics :

- Plasmonics (contact: Ludovic Douillard ) .

- Nonlinear Nanophotonics (contact: Celine Fiorini - Debuisschert ) .

- Self-assembled photonic objects (contact: Fabrice Charra ) .

The applications, addressed in various multidisciplinary collaborative projects, are in the areas of energy (photovoltaics, cold lighting), life sciences (optical molecular labels, sensors and actuators), information and communication technologies (integrated nanophotonics, data storage), as well as more forward-looking topics such as optical manipulation of nanosized objects or single-photon, single-electron, single-molecule photonics.
