Bragg reflection
WebSep 12, 2024 · An FBG sensor is a narrowband reflector consisting of a series of periodic gratings with a refractive index different than that of the OF core material, and working as a mirror of the Bragg central wavelength ( λB) [ 1, 7 ]. λB is dependent on the grating effective refractive index, ηeff, and grating period, Λ, as stated in Equation (1). The derived Bragg's law is a special interpretation of Laue diffraction, where the Braggs interpreted the constructive Laue-Bragg interference in a geometric way by reflection of waves from crystal lattice planes, such that the path-difference becomes a multiple of the incident wavelength.
