Spin-Selective Full-Dimensional Manipulation of Optical Waves with Chiral Mirror

摘要

Abstract Realizing arbitrary manipulation of optical waves, which still remains a challenge, plays a key role in the implementation of optical devices with on‐demand functionalities. 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.
