Challenges in the Design and Fabrication of a Lab-on-a-Chip Photoacoustic Gas Sensor
The favorable downscaling behavior of photoacoustic spectroscopy has provoked in recent years a growing interest in the miniaturization of photoacoustic sensors. The individual components of the sensor, namely widely tunable quantum cascade lasers, low loss mid infrared (mid-IR) waveguides, and effi...
