Transverse localization of light for single-mode and secure information transport

Not Accessible

Your library or personal account may give you access

Abstract

A single-photon beating with itself can produce even the most elaborate optical fringe pattern. However, the large amount of information enclosed in such a pattern is typically inaccessible, since the complete distribution can be visualized only after many detections. In fact this limitation is only true for delocalized patterns. Here we demonstrate how reconfigurable localized optical patterns allow to encode up to 6 bits of secure information in disorder-induced high transmission channels loaded with single photons.
