摘要: 文章提出了一种基于相变材料Ge2Sb2Te5 (GST)的全介质手征超表面。该结构由尺寸相同但取向各异的GST方形开口环谐振器组成，谐振器单元间以氟化镁(MgF2)介质层进行隔离。该超表面对线偏振与圆偏振入射波均展现出显著的手征响应。数值仿真结果表明：在线偏振波入射条件下，其工作波段位于近红外范围，最大不对称传输系数(asymmetric transmission, AT)达0.8，调谐范围达420 nm；在圆偏振波入射时，最大圆二色性(circular dichroism, CD)达0.81，调谐范围达275 nm。本研究对基于GST的可调谐功能器件研究具有重要参考价值，同时在低损耗、多功能光子器件领域展现出广阔的应用前景。
Abstract: In this paper, we propose an all-dielectric chiral metasurface composed of phase-change material Ge2Sb2Te5 (GST) square split-ring resonators (SRRs) with identical sizes but different orientations, sandwiched between magnesium fluoride (MgF2) dielectric layers. This metasurface exhibits strong chiral responses to both linearly and circularly polarized incident waves. Numerical simulations reveal that it operates in the near-infrared spectral range, achieving a maximum asymmetric transmission (AT) of 0.8 with a tuning range of 420 nm under linearly polarized wave incidence, and a maximum circular dichroism (CD) of 0.81 with a tuning range of 275 nm under circularly polarized wave incidence. This study has significant implications for the research on tunable functional devices based on GST and potential applications in low-loss and multifunctional photonic devices.
