Paper Abstract

Novel optical fiber torsion sensor based on LPG pair was proposed and the effect of the twist angle on the torsion was characterized. The transmission of the fringes at peak wavelengths was changed by the twist of the optical fiber with the LPG pair and it is attributed to the polarization dependence upon the twisting of the fiber. The variation of the transmission depends on the input polarization state, which is affected by the applied torsion.
