Traditional optical systems face challenges with inefficiencies, distortions, and bulky designs. These issues are particularly pressing in rapidly evolving fields like augmented reality (AR), virtual reality (VR), and optical communications, where high performance and miniaturization are key. This patented method leverages directed self-assembly (DSA) of block copolymers to fabricate ring-shaped nanostructures embedded with metallic nanoparticles. These nanorings exhibit advanced optical properties, including the ability to generate orbital angular momentum (OAM), enabling high-density data transmission and improved light manipulation.
