Abstract

A metasurface in the metal-insulator-grating configuration is designed and optimised to support enhancement of coherent Raman signal of selected molecules orders of magnitude above the single-molecule detection threshold. The tunability is demonstrated by adjusting the structure to match selected Raman peaks of rhodamine, however, its spectral response is broad enough to cover a range of Raman shifts. Finally, the grating allows switching between distinct values of Raman shift with a single metasurface illuminated at different angles.

超越单分子检测水平的拉曼光谱多共振超表面
设计并优化了金属-绝缘体-光栅结构的超表面,以支持在所选分子的相干拉曼信号的增强,其数量级高于单分子检测阈值。通过调整结构来匹配罗丹明的拉曼峰来证明其可调性,然而,它的光谱响应足够宽,可以覆盖拉曼位移的范围。最后,光栅允许在不同角度照射单个超表面的不同拉曼位移值之间切换。
