Harnessing disorder and symmetries in multimode fibersSébastien M. Popoff
We present how to study light propagation in multimode fibers using transmission matrix measurements and apply it to understand the effect disorder and its impact on the so-called rotational memory effect. This talk is part of the Wave Propagation and Control in Complex Media 2024 workshop (15-19 April 2024, Cargèse, France) |

Spatiotemporal control of lightJoel A. Carpenter
Gerchberg-Saxton is a phase retrieval algorithm, which attempts to retrieve the phase corresponding to two intensity images taken in the near and far-field respectively. It can also be used for calculating computer-generated holograms (phase masks) that generate a desired. |

Learning and Avoiding Disorder in Multimode FibersSébastien M. Popoff
In this work, we demonstrate the existence of a set of spatial channels in multimode fibers that are robust to strong local perturbations. We show that, even for a high level of disorder, light propagation can be characterized by just a few key properties. Related article: doi.org/10.1103/PhysRevX.11.021060 |
