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 […]



Summary

Scientists have overcome a long-standing constraint in optics by independently manipulating light’s wavelength and angle. Using bilayer metagratings, they’ve decoupled these traditionally linked properties. This breakthrough is significant because controlling both wavelength and angle is vital for advanced optical technologies. Separating these characteristics provides new possibilities for light manipulation, potentially revolutionizing fields requiring precise optical control.
