Cover Story (view full-size image): The gas sensor market is growing fast, driven by many social, economic, and industrial factors. Optical gas sensors operating in the mid-infrared spectral region offer excellent performance for an increasing number of potential applications in healthcare, smart homes, and the automotive sector. With the emerging trend of miniaturization of optical devices, such sensors could be integrated into smartphones, watches, wearables, or medical devices, to widen their appeal to a much broader consumer application area. In this issue, we discuss major optical sensor technologies and architectures and present a path towards their miniaturization and monolithic integration with a focus on low-cost, low-power-consumption, and high volume manufacturability.
