Rainbow-catching waveguide could revolutionize energy technologies

The image shows a “multilayered waveguide taper array.” The different wavelengths, or colors, are absorbed by the waveguide tapers (thimble-shaped structures) that together form an array.

By  slowing and absorbing certain wavelengths of light, engineers open new possibilities in solar power, thermal energy recycling and stealth technology
