    Optical Orbital Angular Momentum Processors with Electrically Tailored Working Bands In article number 2201013, Xiao Liang, Wei Hu, and colleagues schematically illustrate planar optics that spatially manipulate light in the entire visible range via a patterned polymer‐stabilized cholesteric liquid crystal with a pitch gradient. An electrically tailored working band can be achieved by varying the helical pitch, enabling mode‐division multiplexing compatible with wavelength‐division multiplexing. This strategy is promising for large‐capacity optical communication and parallel information processing.
