Multiple scattering fundamentally complicates the task of sending light through turbid media, as many applications require. This Review summarizes the theoretical framework and experimental techniques to understand and control these processes.
Nonlinearities allow the large number of modes in a multimode fibre to interact and create emergent phenomena. This Review presents the breadth of the high-dimensional nonlinear physics that can be studied in this platform.
Seeing—and consequently imaging—through turbid media such as fog is a difficult task, as multiple scattering scrambles the visual information. This Review summarizes techniques that physically or computationally reconstruct the images.
Collapse models predict that the superposition principle of quantum mechanics breaks down at macroscopic scales. This Review discusses constraints on these models from non-interferometric experiments.
