A Polarization-Multiplexing Metasurface Logic Operator

In this paper, we propose a polarization-multiplexing single-layer metasurface logic operator that enables independent logic operations under the illumination of different linearly polarized waves. A meta-atom capable of independently manipulating orthogonal linear polarization states is designed to operate as a polarization-multiplexing neuron. Furthermore, the proposed metasurface can serve as different hidden layers in these two polarization channels, achieving a total of ten distinct logic operations. The simulation results are in well agreement with the design targets, achieving a high accuracy of 100%. This polarization-multiplexing strategy can further enhance the channel capacity of optical computing and is expected to facilitate its application in all- optical computers, intelligent computing, and other fields.
