Abstract The superior capability of light manipulation makes optical metasurfaces capable high‐quality multichannel displays, demonstrating great potential in high‐security encryption. Different from the previous nanoprinting based on sophisticated nanostructure design, Malus metasurface can obtain meta‐images only by arranging orientations single‐sized nanostructures and thus have gained attention. Here, an encryption scheme is proposed introducing camouflage strategy into design processes...
In this work, we present a novel four-channel coherent optical chaotic secure communication (COCSC) system, incorporating four simultaneous photonic reservoir computers in tandem with demodulation units. We employ quartet of reservoirs that capture the dynamics polarization components (PCs) emitted by driving QD spin-VCSEL. These are realized utilizing PCs corresponding Through these concurrent structures, facilitate high-quality wideband-chaos synchronization across pairs PCs. Leveraging...
Based on small-world network theory, we have developed a brain-inspired photonic reservoir computing (RC) system utilizing quantum dot spin-vertical-cavity surface-emitting lasers (QD spin-VCSELs) and formulated comprehensive theoretical model for it. This innovative comprises input layers, layer, output layers. The layer features four distinct modules that are asymmetrically coupled. Each module is represented by QD spin-VCSEL, characterized optical feedback injection. Within these modules,...
A novel optical encryption scheme based on single-sized nanostructures storing multiple meta-images into different levels is originally proposed and realized by Juan Deng, Bo Yan, co-workers, as shown in article number 2200949. By introducing a camouflage strategy Malus metasurfaces, this research ensures that even if the information decrypted, real still safe. The simple structure, high security, scalability endow metasurface with great potential applications provide new insights for other...
