The radial memory effect in multimode optical fibres We present a study of a novel memory effect in multimode optical fibres, which manifests itself as an output ring of excess energy at the same radius as an input focussed spot. This effect is robust a...

Numerical calculation of the radial and angular part of a optical fibre mode. The electric field intensity is shown as a gradient going from black to green, with overlapping tiny black arrows to show the field orientation. The pattern has a hexagonal symmetry and the arrows appear to swirl around the nodes.
