摘要：
It is challenging to construct nano-scaled meta-structures enabling efficient and versatile electro-optic modulations, especially those related to circular dichroism ( CD), which is useful in detection of chiral molecules and optical manipulation. In this study, we have modeled chiral metasurfaces based on single-crystal LiNbO3 using finite element method. The numerical calculation and characterization indicate that a quasi-BIC(q-BIC) resonance with a high Q-factor optical signal of 9.3 x 10(4) and a peak CD signal of 0.89 at 972.76 nm could be obtained by breaking the structural symmetry of t...
