Long period fiber grating based on periodically screw-type distortions for torsion sensing

A novel long-period fiber grating (LPFG), fabricated by periodically cascading a series of screw-type distortions, is proposed and experimentally demonstrated. These screw-type distortions are induced by twisting the fiber during CO laser beam exposure. The resulting LPFG will either be left- or rig...
