Fig. 2 All-in-one crosstalk-free metasurface fabrication by fs-LMDW and advanced high-security encryption and decryption. (a) Fabrication processing flow of fs-LMDW in air and EG to encode infrared and visible information. (b) Scheme of crosstalk-free modulation mechanism in Vis/IR bands. (c) Schematic illustration of thermal-driven stepwise IR-information decryption process and Vis-information erasure and final read website encrypted by scanning QR code by a cellphone at 300℃ as well as scheme of erasability and rewritability and the relationship between the Vis-display performance and the security of encrypted information. (e) Visible (top) and IR (bottom) images at increased temperatures from room temperature to 300℃. (f) Erased and rewritten visible information and corresponding IR images of the non-influenced IR code.
