Since June 2021, I administrate the Photonic & Materials Team, composed of 4 research groups.

Scientifically, I focus on problems related to Electromagnetism in micro and nano optical systems (theory and numerics), with the purpose to :

  • Learn and Control the dynamics of classical & quantum objects trapped in levito-dynamics setups, e.g. to make new (quantum or classical) sensors. Work with the experimental  Nano-Optics Group

On-going ANR Project QLevio  :    Reaching the Quantum Ground State of an optically levitated  nanomechanical oscillator (

  •  Design optical nano-systems based on organic materials (e.g. light sources, nanolasers, polaritonic LEDs, etc ….). Work with the experimental  PULS Group and TIPI Group

On-going ANR Project IDOL : Design and Fabrication of Organic Lasers pumped electrically

Theoretical / Numerical work in Levito Dynamics

We model the experiments done in the group, solving Langevin equations of the particle(s) in trap beam, coupled to external PID regulators that cool down the particle(s). We investigate the particle dynamics using tools of Statistical Physics and Nonlinear Dynamics.

In recent works, dealing with the rotational degrees of freedom of the trapped nanoparticle, the

Nano-Optics Group  observed  a phase transition between  locked / unlocked states. In this bistability domain, a giant diffusion effect of the rotation speed has been observed and explained by a simple model based on a timescale separation.

Theoretical Work in Nano-Optics

We use an approach based on the regularization of Singular Scattering operators, and the expansion of a compact non-linear eigenvalue problem. The final goal is to obtain a precise modal expansion for the field scattered by nanoparticle(s), see [] .

This work takes a place between Mathematics and Physics, and paves the route for new modeling tools to obtain accurate but scalar models of complex systems, where the (heavy) computation of 6 field components in 3D space, for each frequency and excitation condition (angle, polarization) is replaced by a the computation of a few complex numbers that characterize the system: the QNM Eigen frequencies and some volume integrals of their modes.

The reduction of complexity is drastic, while preserving quantitative modeling.

Eventually, it is the field map of the mode that contains all the information on the spatial variation of fields, whereas the expansion coefficients (often a few of them are needed), contains the information on frequency (or time) variation.
