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.
