Generation and Use of 'Superbeams' in Turbulence and Scattering Applications
Abstract
The objective of this project was to study the generation and optimization of special beam classes in turbulence and scattering applications, with the goal of combining the beneficial properties of such special beam classes to create what are loosely referred to as superbeams . Particular emphasis was given to beam classes that could perform well in free-space optical communications with errors due to optical scintillation (intensity fluctuations) significantly reduced from conventional coherent Gaussian beams. Simulations demonstrated that incoherent beam arrays can perform as well as more general partially coherent fields, therefore simplifying the optimization process significantly. Pseudo-Bessel correlated beams, Airy beam arrays, nonuniformly polarized beams, and vortex beams were each shown to possess advantages in propagation through turbulence.
