COMPLEX MEDIA OPTICS LAB
Principal Investigator : Sylvain GiganThe 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.

Review article
publication of our review article on applications of wavefront shaping and coherent light in Photoacoustics (and vice-versa), written by S. Gigan and E. Bossy: E. Bossy and S. Gigan, Photoacoustics with coherent light, Photoacoustics, (2016)
2 PhD graduations
Two PhD students graduated this month : Thomas Chaigne (thesis entitled « Control of scattered coherent light and photoacoustic imaging : toward light focusing in deep tissue and enhanced, sub-acoustic resolution photoacoustic imaging ») and Hugo Defienne (thesis entitled "Quantum walks of Photons in disordered media"). Congrats to them and good luck !

Review of Modern Physics: Mesoscopic Physics meet wave control
long awaited, our review paper with Stefan Rotter is finally out in APS's Review of Modern Physics, and made the cover "Light fields in complex media: Mesoscopic scattering meets wave control" 
Nanophotonics Sciencecamp
during the complex nanophotonics Sciencecamp http://sciencecamp.eu/, several current and past members got together, and we could take and 'past a present' group picture, with only few (dearly missed) persons! 
thesis Defense: Mickael Mounaix
Mickael (very) successfully defended his thesis on Nov 8th, entitled: "Matricial approaches for spatio-temporal control of light in multiple scattering media". Congratulation Dr. Mounaix and good luck for your future endeavors! 
Science publication : a surprising invariant of light in complex media
5 years in the making, our result on experimentally verifying a surprising invariance of light in complex media, namely that the average path length is independent of disorder, is finally published ... in Science! check it out!
