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.
We demonstrate experimentally that the new resonance dips can be generated during the fabrication of CO2 laser written long-period fiber gratings (LPFGs) in a single-mode fiber (SMF) under tension. The dynamic analysis of laser writing process was adopted to study the mechanism of the grating inscription. The new characteristics of grating growth were observed except for the increase of writing efficiency...
We investigate in detail the process of CO2-laser writing of long-period fiber gratings (LPFGs) in unannealed and annealed boron-doped fiber samples by using repeated scanning of CO2-laser pulses. We find that the writing dynamics depends strongly on the CO2-laser energy density and the annealing temperature of the fiber. Our results from analyzing the writing dynamics reveal the relative importance...
We investigate the dynamics of writing long-period gratings in unannealed and annealed boron-doped fiber samples with repeated scanning of CO2-laser pulses. Our results demonstrate clearly the effects of glass structure changes in the writing process.
