Abstract EN
The response of ultrashort-length CO2-induced long-period fiber grating (LPFG) sensors to torsion is reported.
While engraving using CO2 laser radiation, the fiber is submitted to high tension allowing the obtainment of gratings with shorter lengths, down to 2.4 mm, which is almost one order of magnitude lower than the usual.
Also, the fiber is only irradiated in one side, creating an asymmetrical profile leading to highly birefringent gratings.
Sensitivity to axial twists is demonstrated, with values up to 0.15 nm/(rad/m) for the resonant wavelength shift and higher than 0.03 dBm/(rad/m) for the variation in the intensity (attenuation).
Discrimination between rotation directions, clockwise and counterclockwise, was observed.
