Abstract

A Temperature-independent strain sensor based on Four-Wave Mixing (FWM) using Raman fiber Bragg grating (FBG) laser sensor with cooperative Rayleigh scattering is proposed. Two FBG were used to form two linear cavities laser sensors based on Raman amplification combined with cooperative Rayleigh scattering. Due to the low dispersion coefficient of the fiber, it is possible to obtain the FWM using the two Raman FBG laser sensors. This configuration allows the operation as a temperature-independent strain sensor where both sensors are sensitive to temperature but only one of the FBG is sensitive to strain. The FWM efficiency is thus dependent on the applied strain but independent to the temperature.
