Sensing and Demodulation of Special Long-Period Fiber Gratings Induced by Scanning CO2 Laser Pulses
A review of long-period fiber gratings (LPFGs) with special structures induced by scanning CO2 laser pulses in single mode fiber (SMF) is presented in this paper. In the first part, the special structures and fabrication methods of LPFGs are demonstrated in detail. Next, the special LPFG-based senso...
