Communication with Chaotic Lasers

TLDR

Chaotic electronic circuits have demonstrated the feasibility of communication using chaos. This study experimentally demonstrates chaotic communication using an optical system. The authors used an erbium‑doped fiber ring laser to generate 1.53‑µm chaotic light and embedded a 10‑MHz message into it, transmitting it to a receiver that recovered the message from the chaotic carrier. The results show that chaotic optical waveforms enable high‑bandwidth communication of masked information.

Abstract

Recent experiments with chaotic electronic circuits have shown the possibility of communication with chaos. The experimental demonstration of chaotic communication with an optical system is described. An erbium-doped fiber ring laser (EDFRL) was used to produce chaotic light with a wavelength of 1.53 micrometers. A small 10-megahertz message was embedded in the larger chaotic carrier and transmitted to a receiver system where the message was recovered from the chaos. Chaotic optical waveforms can thus be used to communicate masked information at high bandwidths.
