Any Color You Like: NIST Scientists Create ‘Any Wavelength’ Lasers in Tiny Circuits for Light

(Funded by the National Institute of Standards and Technology)
Traditional computer chips have transformed our world by cramming billions of electronic devices into tiny silicon chips. NIST scientists have now made a major advance toward doing the same with light. To make their new chip, the researchers stacked specialized materials on top of each other, creating a high-tech “layer cake.” Called integrated photonic circuits, these chips can transform light, taking in one laser color and putting out a rainbow of colors. This advancement could lead to profound impacts on major industries, including: Quantum Computing, Artificial Intelligence, Navigation and Research.
