Hafnium Oxide-Based Ferroelectric Reconfigurable Optoelectronic Logic Gate Arrays for Optical Communication Encryption

• • The HZO ferroelectric thin films exhibit a pyroelectric coefficient of 1835.91 μC m−2 K−1, enabling highly sensitive photon-to-current conversion for efficient optical signal detection and modulation. • • The OELG device supports five fundamental logic operations (AND, OR, NAND, NOR, NOT) with stable performance over 10^9 cycles without degradation, ensuring long-term reliability for practical encryption systems. • • The CNN-integrated encryption framework achieves 95.01% recognition accuracy on correctly decrypted images, while unauthorized decryption attempts result in severe feature distortion (e.g., 82.18% misclassification as frogs), demonstrating high security. • • The reconfigurable OELG array eliminates the need for hardware modifications to change logic functions, offering dynamic adaptability and hardware flexibility that traditional encryption methods lack.
