Mode Characteristics and Sensing Performance of Fiber Gratings
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.

Single-mode sapphire fiber Bragg grating
Sapphire optical fiber has the ability to withstand ultrahigh temperatures and high radiation, but it is multimoded which prevents its use in many sensing applications. Problematically, Bragg gratings in such fiber exhibit multiple reflection peaks with a fluctuating power distribution.
