Coordinator : Joël Charrier

Research activities in Guided Optics and Sensors (GOS) are organized around the following themes :

The study of miniaturized photonic sensors in the societal fields of health, the environment, and defense for wavelengths ranging from blue to mid-infrared
Hyperspectral imaging
The study of light sources based on nonlinear optical effects and rare-earth ions, operating from the near-infrared to the mid-infrared spectral range
The development of integrated photonics, including simulation tools for guided-light propagation, as well as the design and fabrication of integrated optical devices operating from the visible blue region to the mid-infrared
The study and development of optical coupling and interconnection solutions.

These studies draw upon the team’s expertise in various optical characterization benches at different wavelengths and the associated measurement metrology, in optical coupling and assembly methods, particularly those utilizing microlensed fibers, in simulation and design tools that leverage the optical properties involved, and in the fabrication of optical devices, especially in integrated optics. This work is supported by two platforms associated with the Foton Institute: CCLO and PerSyst.

NV-Center-Based Magnetometry

Nitrogen-vacancy (NV) color centers in diamond possess an energy-level structure similar to that of atoms. Unlike atoms, which are typically used in gaseous form and move freely due to thermal motion, NV centers are embedded within the diamond crystal lattice and therefore remain fixed in position. These artificial atoms can therefore be addressed by lasers… → Read more
