Random Fiber Lasers A multimode-fiber-mediated random fiber laser with 100+ watt output power was demonstrated for speckle-free imaging, as presented by Shanshan Wang, Weili Zhang, Yunjiang Rao, and co-workers in article number 2100390. combined multimode provides a powerful platform to realize advanced lasers controllable spatial characteristics, which is of great significance applications ima...

Topological insulators feature a number of topologically protected boundary modes linked to the value their bulk invariant. While in one-dimensional systems are zero dimensional and localized, two-dimensional topological chiral, propagating along edges system. Thus, photonic with large Chern numbers naturally display multimode waveguide at edges. Here, we show how take advantage these by interf...

A number of optical signal processing techniques are reviewed which allow to realise high-capacity multi-service multimode fibre networks in the user environment.
