• Towards Optical AI Architectures: First Robust 3D Photonic Topological Insulator Developed at ITMO

  Scientists from ITMO University have become the first team to create a nonconductive structure that makes it possible to control light in a 3D space without losses, even when the material has defects. It’s a fully dielectric 3D photonic topological insulator that paves the way for new compact, scalable, and robust photonic components, including integrated circuits and optical chips. In the future, they may become the key hardware foundation for next-gen computational AI architectures. The results of the study were published in Nature Materials.
