Light Propagation in complex media gives rise to several non-trivial phenomena due to wave interferences, that can be connected to the domain of mesoscopic physics, usually explored in electronic systems. Among many, one can cite Anderson Localization and the existence of open channels of transmission, two highly non-intuitive phenomena that strongly modify the conduction properties of a disordered system for waves. While the transmission matrix developed in our group can be used to probe such phenomena, and have been, our group have focused on probing the temporal behavior of light in a complex media. PastedGraphic-4
