Abstract
Facing the escalating demands for high-capacity and high-security optical information storage and encryption, meta-optics-enabled multidimensional multiplexing offers a promising solution due to its unprecedented light manipulation capabilities. However, current strategies confine incident directions to orthogonal angles, leaving the potential of nonorthogonal angles unexplored. Here, we propose a phase hybridization and encoding methodology that enables nonorthogonal incidence by analyzing detour-phase relationships and optimizing their phase hybridization. By integrating nonorthogonal incident angles with wavelength and polarization multiplexing, we realize a three-dimensional encryption meta-optics system that reconstructs up to 24 holographic channels within the same field of view. The proposed angular-multiplexed multidimensional encryption strategy not only enhances optical information capacity but also significantly improves encryption security, as decoding is only possible under the correct combination of three optical decryption keys. We envision that the proposed meta-optics platform offers a cutting-edge pathway for advanced data storage, optical encryption, and display technologies.
