Current activity : Ph.D student

Since october 2016 I am a Ph.D Student at Laboratoire Jean Kuntzmann (LJK) in the CVGI team. This thesis is funded by the Commissariat à l'Energie Atomique et aux énergies alternatives (CEA) and under the supervision of Edouard Oudet (LJK), Charles Dapogny (LJK), Alain Glière (CEA) and Karim Hassan (CEA).

My study concern the shape optimization of nanophotonics devices developped at the DOPT department of CEA LETI. These kind of devices are about a couple of micrometers wide and can process an incoming electromagnetic waves in order to carry out some operations (polarization, demultiplexing, splitting etc.). At this scale the waves follows Maxwell equations and are only affected by the refractive index of the materials in which they are moving. The purpose of my thesis is therefore to optimize the distribution of each materials (in practice air and silicon) in order to optimize the optical treatment of the wave.
