A highly sensitive torsion sensor based on long period fiber grating (LPFG) fabricated by 800nm femtosecond laser pulses is proposed and demonstrated. LPFG with an attenuation depth of ∼14dB is achieved within the wavelength range of 1425–1575nm. The experiment results show that the LP02 and LP03 resonant wavelengths experience red-shift when the twist direction is clockwise while they occur blue-shift...
With the alignment of the fiber core systems containing dual-CCDs and high-precision electric displacement platform, twisted long period fiber gratings (T-LPFGs) were fabricated in two different twisted SMF-28 fibers by femtosecond laser. The torsion characteristics of the T-LPFGs were experimentally and theoretical investigated and demonstrated in this study. The achieved torsion sensitivity is 117...
