Harvard researchers developed optical nano-antennae to tune display colors depending on polarization
Harvard researchers developed a new kind of tunable color filter that uses optical nanoantennae to control color output. A single active filter under exposure to different types of light can produce a range of colors.
Kenneth Crozier, associate professor of electrical engineering at the Harvard School of Engineering and Applied Sciences (SEAS), and colleagues engineered the size and shape of metal nanoparticles so that the color they appear depends on the polarization of the light illuminating them. Harvard has named the nano structures chromatic plasmonic polarizers.
