However, it is hard to independently manipulate multiple dimensions of optical waves because the optical dimensions are basically associated with each other when adjusting the optical response of the devices. Here, the concise design principle of a chiral mirror is utilized to realize the full‐dimensional independent manipulation of circular‐polarized waves. By simply changing three structural variables of the chiral mirror, the proposed design principle can arbitrarily and independently empower the spin‐selective manipulation of amplitude, phase, and operation wavelength of circular‐polarized waves with a large modulation depth. This approach provides a simple solution for the realization of spin‐selective full‐dimensional manipulation of optical waves and shows ample application possibilities in the areas of optical encryption, imaging, and detection.This work was supported by the National Key Research and Development Program of China (2016YFA0301102 and 2017YFA0303800), the National Natural Science Fund for Distinguished Young Scholar (11925403), the National Natural Science Foundation of China (11974193, 11904181, 11904183, 91856101, and 11774186), Natural Science Foundation of Tianjin for Distinguished Young Scientists (18JCJQJC45700), the National Postdoctoral Program for Innovative Talents (BX20180148), the China Postdoctoral Science Foundation (2018M640224 and 2018M640229), and 111 Project (B07013).
