Optical multi-sensors
Ultra-miniaturized, high-performance optical multi-sensors for gas & liquid detection
CEA-Leti has worked on innovative photonic sensing technologies for many years. One result of this expertise is the development of new generations of miniaturized, optical photoacoustic and interferometric sensors:
-
Photoacoustic sensors using quantum cascade lasers: By using the thermal laser excitation of a gas or a liquid, it is possible to selectively determine very low concentrations (down to sub-ppm) in real-time.
-
Interferometric Mach-Zehnder sensors: By adsorbing molecules onto arrays of SiN waveguides, it is possible to measure in parallel concentrations for a wide variety of chemical species.
CEA-Leti develops novel sensor solutions from low technology readiness levels (TRL) up to demonstrated proof of concepts (TRL 4-5). Our innovative R&D covers topics such as modeling, design, prototyping, manufacturing and characterization methods from components to sensing systems.
