One Tiny Structure Just Broke a Fundamental Rule of Optics

Scientists have broken a fundamental limit in optics by decoupling angle and wavelength using innovative bilayer metagratings. Wavelength and the direction in which light travels (angle) are two essential characteristics that define how light behaves. Gaining precise control over both of these properties is critical to the function of many advanced optical technologies. However, in [...]
