Extreme events in forced oscillatory media in 0, 1 and 2 dimensions
S. Barland, M. Brambilla, L. Columbo +14
One of the open questions in the field of optical rogue waves is the relevance of the number of spatial dimensions in which waves propagate. Here we review recent results on extrem…
Speckle characterization in a cinematography projection configuration
Pierre Walczak, Xavier Hachair, Stéphane Barland
Due to high exploitation costs and other environmental issues, it would be desirable to phase out large cinema projection systems based on standard xenon lamps in favor of laser ba…
Real time observation of granular rock analogue material deformation and failure using nonlinear laser interferometry
Pierre Walczak, Francesco Mezzapesa, Abderrahmane Bouakline +3
A better understanding and anticipation of natural processes such as landsliding or seismic fault activity requires detailed theoretical and experimental analysis of rock mechanics…
Extreme events induced by collisions in a forced semiconductor laser
Pierre Walczak, Cristina Rimoldi, Francois Gustave +5
We report on the experimental study of an optically driven multimode semiconductor laser with 1~m cavity length. We observed a spatiotemporal regime where real time measurements re…
Nonlinear random optical waves: integrable turbulence, rogue waves and intermittency
S. Randoux, P. Walczak, M. Onorato +1
We examine the general question of statistical changes experienced by ensembles of nonlinear random waves propagating in systems ruled by integrable equations. In our study that en…
Optical Rogue Waves in integrable turbulence
Pierre Walczak, Stéphane Randoux, Pierre Suret
We report optical fiber experiments allowing to investigate integrable turbulence in the focusing regime of the one dimensional nonlinear Schrödinger equation (1D-NLSE). Our experi…
