Abstract

We demonstrate an all-optical solution for secret sharing based on metasurface holography. Metasurfaces are used as separable shares that reconstruct a secret after combination. The inherent alignment sensitivity can be used to build optical rulers.

Quantum metasurface holography

Jia-Zhi Yang, Rongxuan Zhao, Zhe Meng +4 more

Metasurface holography has great application potential in the fields of optical display, optical storage, and security. Traditional metasurface holography uses the well-designed subwavelength structure to modulate the incident laser beam. Although many researches about laser metasurface holography have been realized, metasurface holography based on quantum light sources is rare. Here, we realized quantum metasurface holography through single-photon and multichannel polarization multiplexing metasurfaces, and we compared the quantum results with laser results. Our work proves that quantum light sources can be well modulated by the subwavelength structure of integrated metasurfaces and extend both fields of metasurfaces and quantum optics. This result shows that metasurfaces have the potential for use in various quantum devices to reduce the size of quantum devices, improve quantum efficiency, and enhance practicability, reliability, and accuracy.

Channel shared information encoding with wavelength multiplexed metasurface

Zhenfei Li, Weiren Zhu

Multi-channel information encryption technology has been implemented by metasurfaces owing to their superior capability in manipulating phase, amplitude, wavelength and polarization of incident light. However, any non-full-channel decoding may lead to the leakage of secret information. To further improve the security of information, in this paper, we propose a channel shared information encoding scheme by integrating visual secret sharing scheme with metasurface-based phase-encoding technique. The secret information can be reconstructed only by decoding all the wavelength channels of the metasurface, whiles meaningless images would be extracted in other channel decoding processes, without revealing any original information. The simulated results show the feasibility and adjustability of our encryption system, which can be potentially applied in future optical information security systems.

Optical secret sharing by multi-step liquid crystal planar doublet panning and coupling

Zhichang Mo, Yi Chen, Xiangyu Zhu +5 more

The hologram, which is formed by phases coupled through cascade devices for secret information sharing, still carries a cracking risk.We propose a liquid crystal planar doublet as the information carrier, and new holograms generated by the new coupled phases when the relative displacements of the different liquid crystal layers change.The designed geometrical phases are generated by an optimized iterative restoration algorithm, and each holographic image formed by these phases is readable.This scheme achieves an increase in the capacity of the stored secret information and provides more misdirection, which is expected to have potential value in optical steganography and storage.

Hanbury Brown and Twiss-type optical secret sharing

Zhiyuan Ye, Chen‐Xin Ding, Xue‐Jiao Men +2 more

Towards growing challenges of information security and authentication, various optical techniques based on holography, diffraction, interference, metasurfaces, etc., deliver promising solutions with low energy consumption and parallel high-speed information processing. Here, we report on a new dimension–second-order coherence found in the well-known Hanbury Brown and Twiss (HBT) effect–for performing optical authentication and secret sharing. We develop a method to generate a pair of correlated phase-only masks, each of which is distributed to a shareholder and can produce a specific pattern as authentication under coherent illumination, while two secret images are encrypted in the mutual information of two masks. By combining two masks in two configurations, two secret images can be extracted through spatially cascaded display under coherent illumination and intensity correlation under incoherent illumination, respectively. Conspicuously, two extremes of coherence–spatially coherent or incoherent–will enable the encoding and decoding of two different images with the same phase masks, indicating that the first-order and second-order coherence can be two independent channels for optical cryptography just like other degrees of freedom of light (e.g., polarization). Moreover, we demonstrate a polarization-multiplexing scheme to achieve polarization-selective HBT-type optically secret-sharing with increased capacity, and this type of polarization-phase masks can be readily replaced with metasurfaces.
