(Phys.org) —All objects' colors are determined by the way that light scatters off of them. By manipulating the light scattering, scientists can control the wavelengths at which light is transmitted and reflected by objects, ...
Chips that use light, rather than electricity, to move data would consume much less power—and energy efficiency is a growing concern as chips' transistor counts rise.
