我们已经证明，集成到单个金芯片上的光栅热发射的正交偏振双色红外波为简单高效的化学分析开辟了道路。每个分量光栅均由宽度约为100 nm、深度接近1 μm的高深宽腔构成，并通过表面等离子体激元的器官管共振产生线偏振窄带中红外光。基于确定液体中特定化合物浓度的模型实验，已经证明了集成光栅发射器用于非色散红外分析的有效性。 (C) 2008 年美国物理研究所。
We have demonstrated that orthogonally polarized two-color infrared waves thermally emitted from gratings integrated onto a single Au chip open a way for simple and efficient chemical analysis. Each component grating is made of high-aspect cavities with a width on the order of 100 nm and a depth close to 1 mu m, and generates linearly polarized and narrow-band midinfrared light by the organ pipe resonance of surface plasmons. Effectiveness of the integrated grating emitters for nondispersive infrared analysis has been shown on the basis of a model experiment for determining the concentration of a specific chemical compound in liquids.
