Miniature Trace Gas Analyzers with FFP microcavities

ended

Fiber Fabry-Perot (FFP) microcavity technology developed in the ERC project EQUEMI enables hand-held gas analyzers based on cavity-enhanced laser spectroscopy with a combination of small size and high performance that does not exist in any commercial instrument today. Furthermore, the FFP principle also enables fiber-coupled arrays of cost-effective, passive remote sensors read out by one central unit using scalable fiber multiplexing technology developed for the telecom market. Both features enable fast, easy and cost-effective emission measurements of GHG and other trace gases in areas where they are not practically feasible today. Finally, the microscopic size of FFP cavities means that extremely small gas samples (below one microliter cavity volume) can be analyzed and high bandwidth can be achieved with low gas throughput. Here we propose to demonstrate the performance of such instruments by building a demonstrator for methane detection, investigate market potential and prepare commercialization with a team of founders that is already in place.
