Singapore scientists leverage 200-year-old experiment for future computing

Scientists at Nanyang Technological University in Singapore have successfully produced complex optical structures known as photonic skyrmions using a simple method that involves directing a laser beam onto a small circular disk. This approach avoids the costly synthetic materials that were previously used. The study shows that these structures can take on four different topological patterns within a Bessel spot—a historic optical phenomenon that demonstrates the wave nature of light. These patterns remain stable and can be utilized for information carrying and secure data transmission, all while reducing costs and simplifying production processes. This development could pave the way for future optical communication and data storage systems.
