摘要

利用带间级联发光器件(ICLED)和谐振腔红外探测器(RCID)的结合，我们在19°C和4.0µm条件下实现了400 ppmv N2O (5.5× 10 - 5吸光度)的检测限。这些结果证明了将icled和rcid结合在一个大规模生产的光学气体传感芯片上的可行性。

Room temperature detection of N2O using a resonant cavity mid-IR detector and interband cascade LED

We achieved a detection limit of 400 ppmv N2O (5.5× 10 − 5 absorbance) at 19 °C and 4.0 µm, using emission from an interband cascade light-emitting device (ICLED) in combination with detection by a resonant cavity IR detector (RCID). These results demonstrate the feasibility of combining ICLEDs and RCIDs on a single mass-produced chip for optical gas sensing.
