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

  • Quantum Technologies & Communications (see for ex. [1],[2],[3])
  • Interferometric Optical Sensing, OTDR Temperature and Strain Sensing, Acoustic Sensing, Oil and Gas Exploration
  • Optical Coherent Communications ([4])
  • Spectroscopy
  • Frequency metrology

Prospective applications of fiber optics interferometer include testing the interplay between general relativity and quantum physics with light [5].

Long optical delay line is also proposed to be used for the detection of dark matter [6] [7]

Fiber interferometers are also used in ARTEMIS for the future laser interferometer gravitationnal wave detector in space LISA. A spatialy resolved stray light detection system has been developped to characterize the main optical systems of LISA (see [6] and ARTEMIS LISA group web page )

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.
