In this chapter, we introduce and review the technology of Bragg gratings in optical fibres. We detail the aspect of photosensitivity in optical fibres, the properties of Bragg gratings, and the
This chapter reviews the theory of fiber Bragg gratings. A fiber Bragg grating of a constant refractive index modulation and period therefore has an analytical solution. A complex
This particular grating had a very weak index modulation, resulting in a narrow-band reflection filter at the writing wavelength. In reality, this phenomenon happened by chance, when they injected a high

To manage the non-uniform case, the grating is divided into a sequence of short uniform gratings, each one having properties approximately equal to the local values of the non-uniform grating.
The FBG formula A variation of the period of the grating inscripted in a fiber optic – induced by mechanical or thermal perturbation – causes a shift of the reflected peak wavelength, due to the
Theory of Fiber Bragg Gratings Wave propagation in optical fibers is analyzed by solving Maxwell''s equa-tions with appropriate boundary conditions. The problem of finding solu-tions to the wave
Bragg gratings are reflecting structures with a periodic refractive index modulation. They are contained in dielectric mirrors and in some fiber devices.
