Nonlinear Upconversion Technique for Monitoring Environmental Gases

QLM is proud to announce the continuation of our research collaboration in gas detection exploiting 2nd generation quantum technology. Innovate UK and Department for Environment, Food and Rural Affairs (DEFRA) are supporting our research under the Environmental Monitoring Innovation fund. The “Nonlinear Upconversion Technique for Monitoring Environmental Gases” (NUTMEG) project builds upon our previous research collaboration with Covesion Ltd. , Fraunhofer Centre for Applied Photonics and University of Bristol on the ‘UP-SENSE’ project. This approach uses photonic up-conversion single-photon spectroscopy for gas sensing. Optical waveguides in non-linear materials developed by Covesion enable the quantum process of up-conversion of photons from short-wave infra-red (SWIR) to visible wavelengths, facilitating detecting light with efficient single-photon avalanche detectors, whilst interrogating for the presence of gas at more sensitive SWIR wavelengths. The NUTMEG project will develop, construct and test a portable greenhouse gas sensor for environmental monitoring applications. Working with Covesion and Fraunhofer, we will demonstrate a platform approach targeting CO2, Methane, NOx and Ammonia monitoring. https://lnkd.in/et96q4BC
