CAPTEURS ACOUSTIQUES PLASMONIQUES MULTIMODALES (MULTIPAS) MULTIMODAL PLASMONIC ACOUSTIC SENSORS (MULTIPAS)

The aim of this doctoral thesis is the design and optimization of an integrated acousto plasmonic system to create a multimodal biosensor having a highly sensitive with wide dynamic range through usage of the elasto-optic effect. The idea is to explore the interaction between surface acoustic waves (SAWs)and localized surface plasmons in a multilayer structure containing spatiallylocalized functionalization on nanostructured surfaces. The study may identify specific acoustic modes that strongly couple with plasmons, leading to significant modulation of physical parameters of plasmon frequency modulation. This will inevitably require a good understanding of the physics involved, so as to be able to carry out simulation stages before manufacturing and characterization

The thesis will be conducted between the following laboratories:

• Laboratoire Nanotechnologies et Nanosystèmes (LN2 – IRL 3463 CNRS),University of Sherbrooke, Quebec, Canada.

• Institut Jean Lamour (IJL - UMR 7198 CNRS), University of Lorraine, France

The thesis will be jointly supervised by the two universities. Both laboratories are equipped with clean rooms and the technology necessary for the successful completion of the thesis. These two laboratories have already worked together on two theses and an ANR project and publish jointly. Collaborations with partners in Université Paris-Saclay will be possible during the thesis.
