Fiber Bragg gratings have a periodically altered refractive index to filter certain wavelengths while allowing others to pass. Fiber Bragg gratings (FBGs) are widely used in telecommunication, sensor, ...

Fiber Bragg gratings are used to stabilize the output of a laser and to filter out wavelengths in a WDM system. The name comes from Bragg's Law, which is used to create the spacing of the changes.

Traditional optical fibers, whose refractive index of core is higher than that of the cladding, confine light field by the total internal reflection. Yeh et al. proposed Bragg fiber (Fig. 3.51) in ...
