Originally, the manufacture of the photosensitive optical fiber and the ''writing'' of the fiber Bragg grating were done separately. Today, production lines typically draw the fiber from the preform and ''write'' the

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.
