Missions

In non-linear systems, noise can induce new regimes leading to the formation of synchronized structures, consistency between the output and input of resonators or even the amplification of weak signals. In other words, noise and chaos can play a constructive role, with potential benefits for signal processing or detection for example. The chaos in the optomechanical system might be relevant for ultra-precise measurements or fundamental tests on the physical conditions of classical dynamics. Because regular chaotic mixed dynamics are sensitive to small variations in system parameters (system mass, external induced noise, etc.), such variations can be detected by a drastic change in membrane dynamics. For example, these could find use in applications such as random number generation and secure communication as well as chaotic optical detection.

Activities

- design of optomechanical resonators
- Manufacturing in a clean room
- Optical study of nonlinear and chaotic dynamics

Skills

- optical experimentation
- knowledge in nanophotonics & optomechanics
- cleanroom work experience

Work Context

The post-doctoral fellow will be involved in numerical simulations of nonlinear and chaotic dynamics. The C2N cleanroom manufacturing will also be part of the project. She will also be involved in the experimental developments necessary to simultaneously address several resonators allowing the study of synchronized behavior.
