1. Breakthrough in Optics: Decoupling Angle and Wavelength with Bilayer Metagratings

Scientists have achieved a groundbreaking feat in optics by decoupling angle and wavelength using innovative bilayer metagratings. This breakthrough overcomes the fundamental challenge of angle-wavelength locking, which has long been a barrier in advanced optical technologies. The research, led by Professor Jian-Wen Dong from Sun Yat-sen University and Lei Zhou from Fudan University, introduces a novel design that preserves spatial inversion symmetry while breaking vertical mirror symmetry. This allows for precise angular control of radiation directionality, enabling independent selectivity of angle and wavelength. The team also developed a sophisticated fabrication approach to create high-quality bilayer metagratings, demonstrating high reflectance at a single angle and wavelength. This research opens new opportunities for applications in AR/VR displays, spectral imaging, and advanced semiconductor manufacturing.
