WebApr 1, 2024 · The SHG and SHG-CD are achieved from a chiral metamaterial under circularly polarized excitation. • The SHG follows the conservation of parity when the parity of the chiral metamaterial changes. • The maximal modulation depth of the ellipticity and the polarization rotation angle of the SHG reach 91% and 72°. Abstract WebSep 1, 2024 · The SHG circular dichroism is evaluated by using the formula SHG − CD = 2 I 2 ω RCP − I 2 ω LCP / I 2 ω RCP + I 2 ω LCP [56], [57], where I 2 ω RCP and I 2 ω LCP are the intensities of second harmonics for RCP and LCP pumps, respectively.
