The LCO (french acronym for Optical Sensors Laboratory) develops innovative Silicium integrated photonic components (optical sources, waveguides, photodetectors, etc), sensors, and eventually systems. From upstream technological research to industrial transfers, those sensors apply in various fields such as environment, health, and security.

One of the laboratory research topic is mid-infrared spectroscopy of dense samples, using a photothermal detection technology. As we got convincing results applying our sensors for monitoring humans physiological parameters, we now wish to adapt them to plants. First laboratory trials reveal encouraging results, but their interpretation is at this stage out of reach because of the complexity of the measure, and the case study itself. Tackling this problematic is the thesis objective.

To achieve it, the candidate will establish an experimental program with the help of instrumentation and plant biology specialists. He will have access to the laboratory computational and experimental resources, as well as the CEA-Grenoble prototyping capabilities.
