Optical properties and application of fiber Bragg grating

The varieties and techniques of fiber Bragg grating(FBG)are reviewed in this paper, and it's basic optical properties of reflection,including peak reflection and reflection full width at half maximum (FWHM), are analysed with coupled-wave theory.The results show the FBG has unique optical reflective character .We also introduced it's applications in fiber communication, sensors, filters ,etc. The summary demonstrates the FBG will have important influence on the whole field of fiber technology.
