Scanning electron micrographs of the fabricated left and right-handed chiral metasurface structures (a) left-handed; (b) right-handed. The insets show a unit cell of the chiral metasurface. (c) Schematic of a spectral CPD measurement setup; (d) Experimental results of the measured transmission of left-handed and right-handed circular polarization incident on the left-handed structure; (e) Experimental results of the measured transmission of left-handed and right-handed circular polarization incident on the right-handed structure. (f) Experimental polar diagrams for the polarization state of the transmission with RCP incident light at wavelength 1.56 μm. (g) Experimental polar diagrams for the polarization state of the reflection with LCP incident light at wavelength 1.56 μm.
