DOI: 10.1063/5.0284736

Abstract: Atmospheric turbulence causes beam broadening and beam wander in vortex beams during propagation. Based on the Rytov perturbation theory, the Huygens–Fresnel principle, and the beam wander theory, analytical expressions for the beam width and variance… read more here.

DOI: 10.1117/1.oe.59.5.056103

Abstract: Abstract. When a link budget for Earth-to-space connectivity needs to be prepared for a scenario in which optical technology is used, in terms of atmospheric turbulence random degradation, the most important losses to account for… read more here.

DOI: 10.1364/ol.44.004371

Abstract: We study the beam wander of a class of structured light beams, Hermite-Gaussian correlated Schell-model (HGCSM) beams, in theory and in experiment. It is found that modulating the coherence structure of a structured light beam… read more here.

DOI: 10.1364/ol.564963

Abstract: Twist phase is a unique degree of freedom in partially coherent optical fields, which produces photonic orbital angular momentum (OAM) similar to the vortex phase. In this Letter, we report a method for efficiently generating… read more here.
