To trap a rainbow, slow down light
A new material that halts and absorbs light may lead to advances in solar energy, stealth technology, and other fields, experts say.
The “waveguide” developed by a team at the University at Buffalo absorbs each frequency of light, at slightly different places in a vertical direction, to catch a “rainbow” of wavelengths. The technology is essentially an advanced microchip made of ultra-thin films of metal and semiconductors and/or insulators.
