Atmosphere Spectroscopy using Terahertz Sensors dedicated to quantum cascade laser sensing

The project AtSpecTS (Atmosphere Spectroscopy using Terahertz Sensors dedicated to quantum cascade laser sensing) aims o develop a compact, disruptive spectroscopic gas sensor technology for the 2–5 THz range, utilizing advanced field-effect transistor (FET) technology and offer QCL users a new compact and cost-effective solution for atmosphere research. Atmospheric gases like carbon dioxide, methane, nitrous oxide, and atomic oxygen are critical in greenhouse effects, chemical reactions, and energy regulation. Spectroscopy enables precise detection of these gases by analyzing their absorption and emission of electromagnetic radiation. The project focuses on improving the accuracy of gas detection and analysis in the terahertz range, where clearer signals with less spectral overlap can be obtained compared to IR spectroscopy. The expected outcome is a technology that is ready for participation in the next atmosphere research mission.
