Tunable Optical Metamaterial Enables Steganography, Rewriting, and Multilevel Information Storage

Proposed a dynamic grayscale gradient modulation system enabling multi-information analysis and encryption under multi-optical fields, establishing a new paradigm for multi-dimensional encryption of collaborative multispectral information. Developed coumarin-based photo-responsive in situ reconstruction technology and constructed a multi-optical field coupled control system to achieve dynamic configuration of multi-information carriers. Designed and fabricated a micro-dynamic multiple encryption device with integrated functions for information writing, erasing and rewriting, realizing stable information storage and dynamic destruction through micro/nano-optical keys.
