Nanodevice Maps the Angle of Light to Color and Vice Versa – IEEE Spectrum
https://spectrum.ieee.org/nanoclast/semiconductors/nanotechnology/nanodevice-maps-the-angle-of-light-to-color-and-vice-versa An international team of researchers has added a small twist to typical light filters. They’ve fabricated a nanoscale device that divides incident light into its different component colors based on the direction the light is coming from. They’ve switched from making filters with equally spaced grooves to an aperiodic architecture wherein the grooves are not equally spaced. The research →
