SHARE

Fiber Bragg Grating (FBG) works as distributed Bragg reflector (DBR) build on an optical fiber with the help of periodic variation in refractive index of the single mode fiber core. When light is passed through the FBG it will reflect certain wavelength of light and transmits all other. When temperature or strain around Grating changes, shift in reflected wavelength is observed.
