Nanotechnologies

Our team takes part in a larger collaboration with CEA/LETI (Grenoble), initiated by the Inria Project-Team Nachos, and related to the Maxwell equations. Our component in this activity relates to the optimization of nanophotonic devices, in particular with respect to the control of thermal loads.

We have first identified a gradation of representative test-cases of increasing complexity :

  • infrared micro-source

  • micro-photoacoustic cell

  • nanaphotonic device.

These cases involve from a few geometric parameters to be optimized to a functional minimization subject to a finite-element solution involving a large number of dof's. CEA disposes of such codes, but considering the computational cost of the objective functions in the complex cases, the first part of our study is focused on the construction and validation of meta-models, typically of RBF-type. Multi-objective optimization will be carried out subsequently by MGDA, and possibly Nash games.

This research activity is aimed to make our methodologies and application fields more diverse, and we expect to be confronted to novel optimization problematics raised by the specific context.
