Our High-Order Nanostructured Gradient Index Vortex Phase Components (HO-nVPC) are designed for the efficient generation of optical vortices with high topological charges. Developed through sophisticated nanostructuring techniques, these components are capable of converting Gaussian beams into vortex beams with topological charges up to 5 in both visible and near-infrared regions. Optimized for integration into both fiber-optic and free-space optical systems, the HO-nVPC offers exceptional beam quality and precise control over topological charges.
