A chirped fiber Bragg grating is a grating where the period of the index modulation varies continuously along its length. This design is used for applications like compensating chromatic dispersion in fiber
16.3 Fiber Bragg Gratings
In its simplest form, a FBG consists of a periodic modulation of the re-fractive index in the core of a single-mode optical fiber. Its functionality can be derived directly from Maxwell''s equations.
