COMPLEX MEDIA OPTICS LABPrincipal Investigator : Sylvain Gigan
The group focus on light propagation in complex media, where light is scattered in a very complex way, such as paint layers, paper, or biological tissues, multimode fibers. Multiple scattering of coherent light generates extremely complex interference
patterns, called speckle. But despite the enormous complexity of the scattering process, we can exploit and control light propagation, in particular thanks to spatial light modulators and to advanced algorithms tools. Our approach is particularly interesting for imaging, quantum and classical computing, but also as windows to understand subtle mesoscopic physics effects.
