Converting light from one wavelength (or "color") to a shorter wavelength, a process needed for efficient communication and advanced manufacturing, is typically inefficient. To tackle that inefficiency, a team built a specialized, layered structure with tiny metallic cavities that improves the light conversion efficiency by orders of magnitude. The cavities can also alter other characteristics (direction and polarization) of the outgoing light beam.
