The radial memory effect in multimode optical fibres

Optics 2025-08-18 v1

Abstract

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 against fibre perturbations, and we discuss its possible use for spatial multiplexing.
