This work explores an alternative infrared (IR) detection mechanism that is based on the desorption of vapor molecules from the Morpho butterfly nanostructures under the stimulation of incoming IR photons, and demonstrates the use of such stimulated desorption for both broadband and wavelength selective IR detection. Compared to the structural deformation‐based IR detection using the Morpho nanostructures, this detection mechanism enables more than an order of magnitude of improvement in both the response of relative reflectance and also the signal‐to‐noise ratio at the maximum heat‐sink‐free response speed. The stimulated desorption also provides the opportunity to achieve the wavelength selective IR detection due to the wavelength selective IR absorption of the adsorbed molecules. With the demonstrated high performance in both broadband and wavelength selective IR detection, this detection approach can potentially enable other high performance sensing systems, including chemical vapor, biological, energy, and environmental sensing systems.

蝴蝶之翼启发了具有光谱选择性的高性能红外检测

这项工作探索了一种替代的红外（IR）检测机制，该机制基于在入射IR光子的刺激下从Morpho蝴蝶纳米结构中解吸蒸气分子的原理，并演示了这种受激解吸在宽带和波长选择性IR检测中的用途。与使用Morpho进行基于结构变形的IR检测相比在纳米结构的情况下，这种检测机制能够以最大的无散热器响应速度在相对反射率响应和信噪比方面提高多个数量级。由于所吸附分子的波长选择性IR吸收，受激解吸也提供了实现波长选择性IR检测的机会。凭借在宽带和波长选择性红外检测方面都表现出的高性能，这种检测方法可以潜在地启用其他高性能传感系统，包括化学蒸汽，生物，能源和环境传感系统。
