The chiro-optical effects complemented with polarization conservation and wavefront shaping finds potential applications in advanced imaging, sorting and detection of enantiomers and quantum optics. Here, a unique design strategy proposed to manifest enormous chiro-optical effects using achiral structures (instead of conventional chiral antennas). The basic building block of the meta-platform contains a pair of achiral structures. The underlying mechanism behind the giant chiro-optical effects is explained by numerically calculating the multipolar resonances of scattering power. The designed diatomic meta-platform achieves absolute control over spin and wavefront of incident light to demonstrate the polarization-conserved and -encrypted meta-holograms.
