Mode Characteristics and Sensing Performance of Fiber Gratings
Journal of Harbin University of Science and Technology, 2022 Fiber gratings are special optical fibers with a periodic refractive index distribution when the refractive index of the fiber core is modulated. Both the angle and period of the gratings have an influence on the sensing properties of the fiber gratings.

Fabrication of long period fiber gratings of subnanometric bandwidth [PDF]
Optics Letters, 2017 This Letter reports on the fabrication of long period fiber gratings having subnanometric bandwidths in the 1500 nm spectral region. Large gratings have been photo inscribed in a high NA fiber; the grating pitch and the order of the HE cladding mode are optimized to produce gratings with a large number of periods and prevent the coupling to TE, TM, or ...

Arc-Induced Long Period Fiber Gratings [PDF]
Journal of Sensors, 2016 Long period fiber gratings produced by the electric arc technique have found an increasing interest by the scientific community due to their ease to fabricate, virtually enabling the inscription in any kind of fiber, low cost, and flexibility. In 2005 we have presented the first review on this subject.
