Infrared emitters based on MEMS technologies are the best choice for most applications in infrared gas detection. However, the emitters currently available on the market are still too limited in terms of output power, stability, and efficiency to open up further areas of application in the field of organic compounds.
The new EiS research project at the CiS Research Institute aims to develop new technologies for optically enhanced IR emitters. An innovative layer stack is intended to enable increased absorption and emission for a selected IR spectral range relevant to gas detection. This will be implemented in a MEMS IR emitter, which is also expected to have high dynamic range and long service life. The layer stack is also intended to be adaptable for different spectral ranges in the IR region, for which a validated material-based prediction model is being developed simultaneously. The goal is to create an even more miniaturized and cost-effective chip that exhibits at least the same light output as previous chips and can thus open up new application areas.
The research and development work described was funded by the Federal Ministry for Economic Affairs and Energy (BMWE) as part of the research project “Development of Innovative Layered MEMS-IR Emitters” (EiS).
