The structured beams especially with spatially varying phase distribution have attracted
tremendous attention in both physics and engineering. Recently, studies have shown that …

Having shown early promise, free-space optical (FSO) communications face formidable
challenges in the age of information explosion. The ever-growing demand for greater …

Recently, studies have shown that the spatial confinement on waves or photons with beam
shaping techniques would modify the propagation speed of optical fields including both …

Laser beam transmission in atmospheric turbulence causes image distortion and affects the
quality of information transmission in the field of optical communication. The strength of the …

Vortices are ubiquitous in nature and can be observed in fluids, condensed matter, and even
in the formation of galaxies. Light, too, can evolve like a vortex. Optical vortices are exploited …

This study analyzes the efficacy of radio over free space optics (Ro-FSO) communications
over an atmospheric turbulence link. Four transmission channels transmitted information at a …
