| Hi everyone! I’m Arnaud, I come from southeastern France, and I’m currently working in Hannover, Germany, at Leibniz University. For my thesis, I will also be working in Nice, France, at Côte d’Azur University. |
| Let me introduce myself with a few pictures I have chosen. In my region, we are blessed to have both the mountains and the sea. Some friends and I have a tradition of going hiking in the Alps for a few days every summer and I have a strong attachment to Nice, the city where I studied, and the French Riviera. I also enjoy traveling around Europe and discovering beautiful architecture. |
| Optical fibers were designed to transport light over long distances. To minimize losses, scientists have made the glass increasingly pure over the decades. Today, however, we introduce nanoparticles inside the fibers. When light encounters these particles, scattering occurs: the light is sent in all directions in space, with an intensity that depends on the direction. Why are we now intentionally introducing losses? Scattering light can be exploited for applications such as consumer lighting and optical sensing. What about my PhD? The goal is to determine the relationship between the properties of the nanoparticles and the resulting scattering pattern. How? 1️⃣ Design the Nanoparticles: Use advanced algorithms to simulate nanoparticle-embedded fibers and identify which nanoparticles produce the desired scattering behaviors. 2️⃣ Build the fibers: Fabricate the experimentally feasible fibers containing embedded nanoparticles. 3️⃣ Test & Prove: Experimentally measure the response of the fibers and compare the results with the previous simulations. |
