Common Structures of Fiber Bragg Gratings

Home / Common Structures of Fiber Bragg Gratings

A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by creating a periodic variation in the refractive index of the fiber core, which generates a wavelength-specific dielectric mirror. The term type in this context refers to the underlying mechanism by which grating fringes are produced in the fiber.

Bragg Gratings

Bragg gratings are sections of single-mode fiber in which the refractive index of the core is modulated in a periodic fashion, as a function of the spatial coordinate along the length of the fiber.
