Job description
Optomechanical sensors are a groundbreaking class of MEMS devices, offering ultra-high sensitivity, wide bandwidth, and seamless integration with silicon photonics. These sensors enable diverse applications, including accelerometry, mass spectrometry, and gas detection. Optical sensors, leveraging photonic integrated circuits (PICs), have also shown great potential for gas sensing.
This PhD focuses on developing a hybrid multi-physics sensor, integrating optomechanical and optical components to enhance sensing capabilities. By combining these technologies, the sensor will provide unprecedented multi-dimensional insights, pushing MEMS-enabled silicon photonic devices to new limits.
At CEA-Leti, you will access world-class facilities and expertise in MEMS fabrication, photonics, and sensor integration. Your work will involve:
-Sensor Design – Using analytical Tools and simulation software for numerical analysis to optimize device architecture.
-Cleanroom Fabrication – Collaborating with CEA’s expert teams to develop the sensor.
-Experimental Characterization – Conducting optomechanical and optical evaluations.
-Benchmarking & Integration – Assessing performance with optics, electronics, and fluidics.
This PhD offers a unique chance to merge MEMS and silicon photonics in a cutting-edge research environment. Work at CEA-Leti to pioneer next-generation sensor technology with applications in healthcare, environmental monitoring, and beyond. Passionate about MEMS, photonics, and sensors? Join us and help shape the future of optomechanical sensing!
