Abstract:Optical grating devices based on micro/nanostructured functional surfaces are widely employed to precisely manipulate light propagation, which is significant for information technologies, optical data storage, and light sensors. However, the parameters of rigid periodic structures are difficult to tune after manufacturing, which seriously limits their capacity for in situ light manipulation. Here, a novel anti‐eavesdropping, anti‐damage, and anti‐tamper dynamic optical encryption strategy are reported via tuna… Show more
