Fiber Bragg Gratings
Fiber Bragg gratings are reflective structures in the core of an optical fiber with a periodic or aperiodic perturbation of the effective refractive index.
Fiber Bragg grating
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.
Distributed-feedback laser
In DFB fiber lasers, the Bragg grating (which in this case forms also the cavity of the laser) has a phase-shift centered in the reflection band akin to a single very narrow transmission notch of a Fabry–Pérot
DFB Lasers | Technical Guide | SELECTION GUIDE
The Bragg grating, which is the feedback region, is fabricated along the gain region. The grating is then buried under another lower index cladding layer to produce the desired feedback properties and the

Design and realization of high-power DFB lasers
In DFB lasers the current flows through the Bragg grating. Hence, its fabrication, which typically necessitates a two-step epitaxy, must obey much more stringent demands.
