“…Structure of the gratings in PCFs has been a subject of several studies, e.g. (Humbert & Malki, 2002;Fotiadi et al, 2007). Here we describe method for nondestructive analysis of the grating profile based on spectral data taken during the grating fabrication.…”

“…Furthermore, for high temperatures (close to the fiber fictive temperature) it is also possible that changes in the glass structure occur [11][12][13]. Malki et al detected some changes in the glass structure but no variation of the fictive temperature [18].…”

“…Furthermore, it was proposed that the arc discharges could anneal/create stresses in the fiber and could also promote structural modifications in the glass. Humbert and Malki [12] and Morishita et al [13] also attributed the formation of the gratings to structural modifications due to the high heating/cooling rates. The formers also presented detailed results on stress relaxation in the 700-800 • C temperature region.…”

The electric arc technique allows the inscription of long-period gratings (LPGs) virtually in all types of fibers, including non-photosensitive fibers, the case of non-Gedoped photonic crystal fibers being of particular interest. LPGs written in standard fibers using this technique have shown a high thermal stability. Also, the resistance to γ -radiation of LPGs arc-induced in pure-silica-core fibers is being assessed and the achieved results are very promising. We have also demonstrated that the combination of arc-induced LPGs and UV-induced fiber Bragg gratings (FBGs) leads to sampled FBGs that are able to address sensing functionalities with enhanced performance. Therefore, as a result of their properties, gratings induced by arc-discharges can find a wide range of applications in optical communications as well as in fiber sensing.

“…There are many fabrication techniques inducing a permanent change on the refractive index: laser-based inscription systems such as UV [6], femtosecond pulses [7], and CO 2 laser nearinfrared radiation [8], or physically deforming the fiber using other methods such as electric arc discharges [9][10][11], ion implantation [12], or microbends [13].…”

Ultrashort Long-Period Fiber Grating Sensors Inscribed on a Single Mode Fiber Using CO2 Laser Radiation

et al. 2017

View full text Add to dashboard Cite

Sensing performances of ultrashort (as low as 2.4 mm) long-period fiber gratings fabricated with CO 2 laser radiation using commercial single mode fibers are presented. These lengths are, to our knowledge, the shortest of those found in the literature for this kind of sensors, approaching those typical in fiber Bragg gratings. Sensitivity to temperature and refractive index are demonstrated, with performances within the range expected for a single LPFG written on a single mode fiber without any enhancing technique. Analysis on results is made based on both theoretical and experimental data.
