By introducing a degree of freedom on high‐order Poincaré sphere in the form of latitude‐polarization control and locally tailoring the phase and transverse polarization distributions, Enlian Wang, Changqing Xie, Tianchun Ye and co‐workers (see article number 1801415 ) report a single transmission‐type dielectric metalens for producing multichannel spatially nonhomogeneous focused vector vortex beams. Furthermore, a mode demultiplexing system with a mode crosstalk as low as −34.8 dB is realized for quantum experiments.
