NUMERICAL STUDY ON BROADBAND OPTICAL VORTEX BEAM IN THE VISIBLE RANGE USING NANOSTRUCTURED VORTEX PHASE COMPONENTS
Main Article Content
Abstract
In this study, we designed two compact flat-surface nanostructured gradient phase components to generate broadband optical vortex beams in the visible wavelength range. We numerically evaluated the optical performance of these components in air and liquid environments (ethanol). The results show that nanostructured vortex phase components with thicknesses of 7 μm and 8.5 μm can convert Gaussian beams into fundamental optical vortices within certain visible wavelength ranges. These optical vortex properties are preserved when the components are immersed in ethanol, suggesting potential applications in liquid environments such as microfluidics.
Keywords
