Metasurfaces have revolutionized holography by enabling high-density channel multiplexing, positioning them as promising candidates for applications in full-color holographic imaging, optical data storage, and encryption. However, conventional non-interleaved metasurfaces face limitations in the number of controllable dimensions, restricting the channels available in each dimension. Here, a novel high-dimensional multiplexing scheme is introduced that significantly enhances both the channel multiplexing capacity and isolation in non-interleaved metasurfaces. By integrating the Rayleigh-Sommerfeld diffraction (RSD) formula into the Gerchberg-Saxton (GS) algorithm and incorporating gradient descent optimization, the approach achieves precise phase profile control across multiple dimensions-extending the controllable parameters to include wavelength, polarization state, and spatial distance. This method enables simultaneous multiplexing of three polarization channels, three wavelength channels, and two focal plane distances, producing a total of 18 distinct, well-isolated holographic channels with minimal crosstalk. These results showcase the powerful channel multiplexing and isolation capabilities of this non-interleaved metasurface design, underscoring its potential to advance optical color imaging, secure data storage, and high-capacity information transmission, thereby contributing to the development of next-generation intelligent optical devices.
