Overview: 3D-Printed Helixes and THz Photonics Researchers at Lawrence Livermore National Laboratory (LLNL) have made a notable stride in the field of photonics by optimizing and 3D-printing helix-shaped structures as optical materials for terahertz (THz) frequencies. Terahertz technology sits at the boundary between microwave and infrared light, offering the potential to boost data speeds in…
