Developing `Superbeams' for Improved Propagation Through Turbulence
Abstract
Studies of the behavior of partially coherent beams and other special beam classes on propagation through atmospheric turbulence were undertaken. A pair of new tools were developed to study the behavior of special beam classes in turbulence: a generator of partially coherent field realizations and an angular spectrum technique for propagating partially coherent fields in turbulence analytically. These tools were used in preliminary investigations of partially coherent fields and non-diffracting fields in turbulence. The stability and information-carrying ability of vortex beams were studied using multiple phase screen simulations of atmospheric turbulence. The tools developed during this project will facilitate future studies of special beam classes, and the simulation results demonstrate that special beam classes have significant potential for improving optical communications systems.
