When worn overnight, … WebThe perfect optical vortex has successfully aroused substantial interest from researchers for its central dark hollow caused by spatial phase singularity in recent years. However, the traditional methods of combining the axicon and helical phase to generate the perfect optical vortex lead to an additional focus deviation in the tightly focused systems. Here, …
Free-space optical communication with perfect optical vortex …
WebSep 23, 2024 · Abstract: Concentric perfect optical vortex beam (CPOV) is a significant light field which pay much attention. Here, we demonstrate the CPOV beam be used in Free-space optical communications, which can increase capacity at finite aperture. The result shows the CPOV beam could be decoded simply via the conjugate beam interference method.
