Abstract

Free-space optical communications (FSOC) is emerging as a crucial alternative for high data rate networks. With the commercial availability of optical wide band super continuum lasers, there arises an opportunity to enhance the link availability in the presence of strong turbulence. This paper presents a comprehensive analysis of a terrestrial optical link, considering the compounding factor of exploiting the advantages of incoherent beam combining from spatial diverse laser sources. To assess the performance of the optical link, wave optics simulation and perturbation theory are employed and compared. The analysis focuses on exploring the reduction in fade statistics, which is critical for ensuring reliable and robust communication links in adverse atmospheric conditions. Analysis will be conducted over a variety of, ranges, aperture diameters, wavelengths, and levels of turbulence. By leveraging the capabilities of wide band super continuum lasers, the proposed study demonstrates the potential improvements in link availability, throughput, and stability in the presence of turbulent atmospheric conditions. Moreover, the benefits of harnessing incoherent beam combining from spatial diverse laser sources are also considered in the trade space analysis.
