Weiwei Zhang joined the silicon photonics group from September 2017 as a research fellow, focusing on advanced silicon modulator design and fabrication. From 2013, he joined the Center for Nanoscience and Nanotechnology, University Paris Sud (University Paris Saclay) for his Ph.D./Postdoc under ANR POSISLOT project (Erbium-doped material hybrid integration, on-chip optical amplifier), and CARTOON FP7 project (Carbon nanotube photonic devices on silicon). Previously, he received Master degree of nanoscience from École Normale Supérieure de Cachan (2013, now is École Normale Supérieure de Paris-Saclay, University Paris Saclay) and his B.S. from East China Normal University (Shanghai, 2012).
