我们介绍了一种支持多光谱等离子体诱导透明的可扩展超材料介质的构建方法。复合多层介质由具有辐射和亚辐射杂化等离子体模式的耦合元原子组成，通过结构不对称相互作用。引入了一个包含杂化和模式耦合的微扰模型来解释观测到的新光谱特征。通过实验证明了该方法的有效性，并开发了一种能够在横向平面上自动注册多个超材料层的无升降制造方案。这种能同时增强多频域非线性过程的超材料为光学信息处理开辟了新的可能性。
We introduce an approach enabling construction of a scalable metamaterial media supporting multispectral plasmon induced transparency. The composite multilayered media consist of coupled meta-atoms with radiant and sub-radiant hybridized plasmonic modes interacting through the structural asymmetry. A perturbative model incorporating hybridization and mode coupling is introduced to explain the observed novel spectral features. The proposed scheme is demonstrated experimentally by developing a lift-off-free fabrication scheme that can automatically register multiple metamaterial layers in the transverse plane. This metamaterial which can simultaneously enhance nonlinear processes at multiple frequency domains could open up new possibilities in optical information processing.
