摘要
We demonstrate electromagnetic waves following a gravitational field using a photonic crystal. We introduce spatially distorted photonic crystals (DPCs) capable of deflecting light waves owing to their pseudogravity caused by lattice distortion. We experimentally verify the phenomenon in the terahertz range using a silicon DPC. Pseudogravity caused by lattice distortion reveals alternative approaches to achieve on-chip trajectory control of light propagation in PCs.
