Nanowerk  October 16, 2023 An international team of researchers (Japan, Spain) demonstrated electromagnetic waves following a gravitational field using a photonic crystal. They introduced spatially distorted photonic crystals (DPCs) capable of deflecting light waves owing to their pseudo gravity caused by lattice distortion. They experimentally verified the phenomenon in the terahertz range using a silicon DPC. Pseudo gravity caused by lattice distortion revealed alternative approaches to achieve on-chip trajectory control of light propagation in PCs. Their work has far-reaching implications for the world of optics and materials science, and bear significance for the development of 6G communications… read more. TECHNICAL […]
