Ongoing projects

Optical Rogue Waves in Nonlinear Cavities

This project takes place in the framework of the ANR French grant OptiRoc:

https://sites.google.com/site/optirocproject/home

The project aims to address the extended problems of rogue waves in realistic dissipative optical systems, because all physical and natural systems are dissipative in reality.

Two specific purposes:
- to develop optical workbenches based on nonlinear cavity systems with controllable complexity that can be varied in precisely chosen ways,
- to develop both theoretical understanding and experimental demonstration of the regimes for which very intense localized structures exhibiting rogue event signatures can be generated and controlled.


Dual-Comb Spectroscopy with a Continuous Laser

This project is part of a strong collaboration with Nathalie Picqué, Yan Ming and Theodor Hänsch from the MPQ in Garching.

Dual-comb spectroscopy opens up new perspectives in atomic and molecular physics: improvement up to six orders of magnitude in acquisition time, sensitivity, resolution and accuracy compared to state-of-the-art Michelson-based Fourier transform spectroscopy. Dual-comb spectroscopy without moving parts detects the temporal interference between two combs with slightly different repetition frequencies. So far, mode-locked lasers have been used as frequency comb generators. The need for synchronizing, within interferometric precision, the waveforms emitted by two femtosecond lasers requires advanced experimental techniques of optical metrology, thus strongly limiting most of potential applications.

Here we have implemented a new technique for generating two mutually-coherent combs.* The two frequency combs are generated from a single continuous-wave (cw) tunable laser. Therefore the system passively exhibits high mutual coherence without active stabilization. The cw laser is intensity modulated by two electro-optics modulators driven by electrical clocks set at slightly different frequencies.
