The figure above demonstrates picophotonics in the 3D lattice of silicon atoms. The red wave represents the conventional electromagnetic wave propagating in the solid. The blue inner wave represents the new predicted picophotonic wave.  Graphic provided by Dr. Zubin Jacob.

Researchers at Purdue University have discovered new waves with picometer-scale spatial variations of electromagnetic fields that can propagate in semiconductors like silicon. The research team, led by Dr. Zubin Jacob, Elmore Associate Professor of Electrical and Computer Engineering and Department of Physics and Astronomy, published their findings in Physical Review Applied in a paper titled “Picophotonics: Anomalous Atomistic Waves in Silicon.”

“The word microscopic has its origins in the length scale of a micro...
