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.
