摘要：

Achieving kaleidoscopic wavefront controls with a thin flat plate is pivotal for increasing data capacity yet still challenging in integrated optics. An anisotropic metasurface provides an efficient recipe primarily for linear polarization, but is less efficient for multiple functionalities at arbitrary spin states. Here, a strategy of realizing a spin-decoupled high-capacity multifunctional metasurface by multiplexing the frequency and wavevector degree of freedom (DoF) is reported. By integrating both geometric and dynamic phases in split rin...
