Abstract
In this paper, we presents a comprehensive overview of novel long-period fiber gratings (LPFGs) fabricated by using the high-frequency CO2 laser pulses technique for low-cost sensing. These LPFGs have not only better fabrication flexibility, better high temperature capability, much lower cost than those fabricated by the UV exposure method due to the use of relatively inexpensive CO2 lasers and standard telecommunication fibers, but also a number of unique bend, transverse load and torsion characteristics due to the asymmetrical refractive index distribution on the cross-section of the fiber induced by high-frequency CO2 laser pulses, offering greater potential for multi-parameter measurement.
