Areas of technological expertise

Multimode and monomode fibre optic sensor technologies

On-off modulation

Intensity modulation : with bending, numerical aperture, mode coupling variations

 Polarisation modulation : elasto-optical, Kerr, Faraday effects

 Phase modulation : Sagnac, Mach-Zendher, Fabry-Perot interferometers, holographic elements

 Wavelength modulation : Bragg gratings, diffractive optical elements.

Deployment

Localised or continuously distributed sensors

Distributed sensor networks, addressable in wavelength by an interrogator.



Measurands
