The Bending Sensitivity of Long-period Fiber Gratings Written by CO2 Laser under External Tension

摘要：

we studied experimentally the bending sensitivity of long-period fiber gratings (LPFGs) written by CO2 laser under external tension. Not only higher sensitivity was observed, but also the LPFG was sensitive to the bending direction, which can be attributed to the laser-induced asymmetric index modification across the fiber section.
