Abstract

The chirality and chiroptical response of materials have attracted significant attention for their potential to introduce the new science of light-matter interactions. We demonstrate that collective mode formation under modal coupling between localized surface plasmon resonances (LSPRs) with a chiral arrangement and Fabry-Pérot (FP) nanocavity modes can induce chiroptical responses. We fabricated a cluster of isotropic gold nanodisks with a chiral arrangement (gold nano-windmills, Au-NWs) on the FP nanocavities of TiO2 and Au film. The differential absorption of the Au-NWs coupled with the FP nanocavities under left- and right-handed circularly polarized light irradiations in the far field was significantly enhanced compared with the differential absorption without the FP nanocavities. Far- and near-field analyses by numerical simulation revealed that the Au-NWs coupled with the FP nanocavities formed a collective mode in the near field, and the collective mode represented the chiroptical response in the far field. The light field with the large helicity, can be used in chiral light-matter interactions. The concept of collective mode formation using isotropic metal nanodisks coupled with FP nanocavities provides a platform for controlling complex light fields.

材料的手性和自旋响应因其引入光-物质相互作用新科学的潜力而备受关注。我们证明,在具有手性排列的局部表面等离子体共振(LSPRs)与法布里-佩罗特(FP)纳米腔模式之间的模态耦合作用下,集体模式的形成可诱发自旋响应。我们在二氧化钛和金膜的 FP 纳米腔体上制作了一簇具有手性排列的各向同性金纳米盘(金纳米风车,Au-NWs)。在左旋和右旋圆偏振光照射下,在远场中与 FP 纳米空腔耦合的 Au-NWs 的差分吸收比没有 FP 纳米空腔的差分吸收显著增强。通过数值模拟进行的远场和近场分析表明,与 FP 纳米空腔耦合的 Au-NWs 在近场形成了一个集体模式,该集体模式代表了远场的千扰响应。具有大螺旋度的光场可用于手性光物质相互作用。利用各向同性金属纳米盘和 FP 纳米腔形成集体模式的概念为控制复杂光场提供了一个平台。
