Abstract

In recent years, methane detection has become a hot topic due to the strong impact of methane on the global warming and the climate change. There has also been rising interest in the development of new methane sensors, that can tackle the task of sensitive atmospheric methane detection, but are smaller, lighter, and cheaper than the state of the art. Our approach to this challenge is the development an on-chip waveguide sensor, which compensates for the rather short pathlengths possible on a chip with preconcentration of methane in a thin, specially designed waveguide cladding layer.
