Nano-Optic Technology for Enhanced Security

“Nanotech Security [has] created an atoms-thick display that can be read by humans or machines and that shines with the brightness of a typical LED despite using nothing but reflected light.” via @FastCompany.

NOtES exploits an obscure area of physics to accomplish its bright and sharp display, known as plasmonics. Light waves interact with the array of nano-scale holes on a NOtES display—which are typically 100–200 nanometers in diameter—in a way that creates what are called “surface plasmons.” In the words of the company, this means light “[collects] on the films surface and creates higher than expected optical outputs by creating an electromagnetic field, called surface plasmonic resonance.”
