Propagation Dynamics of Orbital Angular Momentum in Turbid Environments(OAM Dynamics)
Abstract
High-capacity communication and high precision sensors in marine environments are vital tools for a wide range of applications including UAV control, marine health monitoring, and infrastructure security. Recent advances in visible light communications, digital signal processing, and space division multiplexing, such as Orbital Angular Momentum (OAM), present a unique opportunity to develop next generation optical technologies that can be deployed for underwater applications. OAM has unique interactions with turbid environments that are not adequately modelled by current scattering theory. This presents a challenge for the development of adaptive optical correction systems and an opportunity for the creation of novel sensor technologies enhanced by OAM or other structured optical fields. In this project, an experimental marine environmental simulator will be developed to study the interaction of OAM with controlled thermally stable and thermally unstable turbid optical links. Buildingon these experimental studies, a novel numerical simulation approach will be developed based on environmental data driven unit cells to allow for the simulation of arbitrary long-distance underwater optical channels. The aim of these simulations is to replace time consuming and expensive field trials that only provide very specific information about the environmental conditions during the time of that field-trial. This project will support the future development of novel communication and sensing technologies that will react to the environment and dynamically shape both opticalbeams and encoded data to mitigate the effects of marine environments on long distance underwater communication channels.
