我们证明了中红外完美吸收器与嵌入在吸收器结构中的分子吸收共振之间的强耦合。在实验和数值上证明了通过分子吸收线调谐完美的吸收共振的抗交叉行为，并使用简单的耦合谐振子模型进行了解析描述。实验、数值和分析结果非常吻合。这种装置为中红外传感系统和主动可调谐的完美吸收装置提供了潜力。
We demonstrate strong coupling between a mid-infrared perfect absorber and a molecular absorption resonance embedded in our absorber structure. Anti-crossing behavior is demonstrated as the perfect absorber resonance is tuned through the molecular absorption line, both experimentally and numerically, and is described analytically using a simple coupled harmonic oscillator model. Excellent agreement between experimental, numerical, and analytical results are shown. Such devices offer potential for mid-infrared sensing systems and actively tunable perfect absorber devices.
