European consortium developed components for miniaturized gas sensors based on Mid-IR spectroscopy
In a H2020-project MIREGAS, Technical Research Centre of Finland VTT Ltd and Tampere University of Technology teams, together with European partners, developed novel components for miniaturized gas sensors exploiting the principle of Mid-IR absorption spectroscopy. In particular, the main advances concerned the development of novel superluminescent LEDs for 2.65 µm wavelength, Photonic Integrated Circuits (PICs) with 1nm bandwidth for spectral filtering at Mid-IR, hot-embossed Mid-IR lenses for beam forming and photodetectors for 2 to 3µm wavelengths. Silicon photonics PIC technology that
