Paper Abstract

In this paper, the fabrication mechanism of Fiber Bragg Gratings (FGBs) in standard SMF-28 telecommunication fibers without hydrogen loading were explored by using point-by-point (PBP) direct writing method based on femtosecond laser with pulse duration of 100fs, 1kHz repetition rate, a central wavelength of 800nm. And more, a series of FBGs were successfully fabricated. The spectral characteristics of FBGs were explored by adjusting grating period, grating length and laser power. And the FBGs with different center wavelengths and periods were fabricated in order to obtain optimal spectral properties. The result shows that the resonant peak intensity is strengthen when the grating length and laser power was improved. This research will demonstrate the potential application of the developed FBGs for use in multi-wavelength fiber lasers and a variety of high temperature applications.
