Description du sujet de thèse
The objective of this thesis is to study the mechanisms of optomechanical coupling in silicon waveguides with a nanometric core. This work will include the development and optimization of simulation tools for the design of these waveguides, combining numerical results with simplified models based on physical principles to identify the optimal dimensions maximizing coupling efficiency.
The research activity will involve a theoretical study of advanced optomechanical structures to understand their fundamental principles and limitations. It will also include the development of simplified models describing optomechanical coupling, intended to guide the optimization of the waveguide geometry. These models will be validated through experimental characterizations.
Contexte de travail
The Center for Nanosciences and Nanotechnologies - C2N (CNRS/University Paris-Saclay) was established on June 1, 2016, from the merger of two leading laboratories in the Paris region: the Laboratory of Photonics and Nanostructures (LPN) and the Institute of Fundamental Electronics (IEF). In 2018, the teams moved into a building located at the heart of the Paris-Saclay Campus.
