Chirality is an intrinsic property of an object that cannot coincide with its mirror image by translation or rotation. In order to realize strong chiral light-matter interactions which are usually weak in natural materials for practical applications, artificial sub-wavelength structures such as metamaterials, metasurfaces, and plasmonic nanostructures have attracted increasing attentions.
