Researchers unlock light-matter interactions at sub-nanometer scales, leading to ‘picophotonics’
This figure illustrates picophotonics in the 3D lattice of silicon atoms. The red wave represents the classical electromagnetic wave propagating in the solid. The inner blue wave represents the new predicted picophoton wave.
