摘要：

We present a novel technique for manufacturing a long-period fiber grating (LPFG) with enhanced torsion sensitivity based on electric arc technique. The proposed method rotates the fiber around its axis of rotation at each electric arc discharge. We experimentally investigated the torsion-dependent spectral response of the produced grating and the results showed that an enhanced linear torsion sensitivity up to 0.197 nm/(rad/m) was achieved, which is higher than that of the conventional arc-induced LPFGs.
