Fiber Interferometer, Laser Metrology and Stabilisation

The research topic "Fiber Interferometer, Laser Metrology and Stabilisation" explores and develops new approaches based on fiber system for :

• Stabilisation of lasers
• Measurement with laser interferometry
• Metrology of lasers and photonic devices

Main applications of ultra low frequency noise lasers and fiber interferometers are :

• Interferometric Optical Sensing
• Quantum Technologies & Communications
• OTDR Temperature and Strain Sensing
• Acoustic Sensing
• Oil and Gas Exploration
• Coherent Communications
• Spectroscopy

These research activities are part of the Engineering of photonic systems domain of INSIS (Sciences of Engineering and Systems Institute) and of the Optics and laser domain of INP (Physics Institute), two institutes of the CNRS.
