Recently, multidimensional metasurfaces, which can modulate multiple optical parameters of input and output lights simultaneously, have aroused intensive interest. Here, we demonstrate switchable images 3D integrated beam splitters based on hyperbolic metamaterials (HMMs). On one hand, a image controlled by helicity wavelengths is achieved arranging HMMs with different polarization conversion performance. the other polarization-multiplexed broadband splitter generated spatially engineering subunit half-plate By integrating multiplexed filter metamaterial, this further realize separation light space wavelength. This cascaded multilayer metamaterial achieves brand new functionality offers more inspiring possibilities for design multifunctional devices in future.
