Group description
The research activities of the Bordeaux Nanophotonics Group aim at understanding, mastering, and using light-matter interactions at the nanometer scale. For this purpose, the group develops ultra-sensitive optical nanoscopy techniques for the detection of individual nanoscale objects, perform the spectroscopy of their electronic excitations, and explore their applications in quantum optics, condensed matter physics and nano-biophotonics.

ADVANCED MATERIALS AND PROCESSES
Collaboration with the Nanophotonics theory groups led by Javier Aizpurua and Rubén Esteban at UPV/EHU on quantum nanophotonics: The interest of photons as building blocks of quantum technologies requires a experimental and theoritical developments addressing the scattering and emission of light at the nanoscale, with special emphasis in the properties of entangled photonics, statistics of light emission, and scattering of non-classical states of light.
Our collaboration addresses the problem of collective effects in the context of light-matter interaction and spontaneous emission from an ensemble of coherently coupled quantum emitters. Progress in the field of nanophotonics has motivated the experimental investigation of superradiance in a broad range of photonic environments. Tailoring collective optical effects allows for enhancing on-demand light-matter interactions at the nanoscale. Tuning the collective spontaneous emission rate of several interacting quantum emitters in specific material platforms will enable the development of novel photonic applications.
