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. Credit: Purdue University/Zubin Jacob Purdue University researchers have discovered new waves with picometer-scale spatial variations of electromagnetic fields that can propagate in …
