摘要： The method of manufacturing the optical fiber having the Bragg grating includes the steps of applying heat from a heat source to a predetermined portion of the optical fiber and thus diffusing impurities existing in a core of the optical fiber into a cladding of the optical fiber, so as to adjust an effective refractive index for a guided mode in the fiber corresponding to a predetermined wavelength, exposing UV light from an optical source to a phase mask having a periodic surface relief structure, and fabricating the Bragg grating having a predetermined period in the optical fiber using diffraction and interference of the UV light due to the periodic surface relief structure of the phase mask.
