Our research projects on "Multi-modal photonics"

We study and implement specialty optical fibers, more specifically multi-mode or multi-core optical fibers. These fibers are realized in our labs, at the technology central FiberTechLille.

Our research deals with numerous subject under the umbrella term "Multi-modal photonics":
