Holographic multiplexing metasurface with twisted diffractive neural network
Meta-disk utilizes structural multiplexing to significantly enhance optical holographic storage capacity, enabling the storage of numerous high-fidelity images. The technology offers potential applications in optical storage and optical computing.
It unveils an inventive volumetric storage paradigm by harnessing the properties of light, such as its wavelength, polarization state, orbital angular momentum, and incident angle, along with versatile optical materials to store data. The findings suggest that bilinear interpolation attains accuracy comparable to more precise algorithms, without a notable increase in computational load, by more extensively leveraging information from surrounding data points. S2) into different twin diffraction domain of the meta-disk and select two twist angles (corresponding to character \(E\) and \(H\)) to observe the evolution of image quality as the noise increases; see simulated results in Fig.
