A Robust Basis for Multi‐Bit Optical Communication with Vectorial Light (Laser Photonics Rev. 17(6)/2023)

Abstract

Multi-Bit Optical Communication with Vectorial Light In article number 2200844, Keshaan Singh, Andrew Forbes, and colleagues outline a new optical communication protocol that exploits spatial patterns of light for multi-dimensional encoding in a manner that does not require the patterns to be recognised, thus overcoming the prior limitation of modal distortion in noisy channels. The result is a new encoding state-of-the-art of over 50 vectorial patterns of light sent virtually noise-free across a turbulent atmosphere that can immediately be extended to optical fibre and underwater links.
