Paper Abstract

An Arc Discharge Erasing (ADE) technique was proposed to erase the refractive index modulation at selective area in Fiber Bragg Gratings (FBGs) and was taken to fabricate Phase Shift FBGs (PSFBGs). The ADE effect and the PSFBGs fabrication technology was demonstrated experimentally first. The capability and fabrication technique was investigated and the full control of the transmission spectral characteristics of PSFBGs, including the peak wavelength position, intensity and bandwidth, was demonstrated. To get optimum technique parameters, the experimental studies were done under different discharge electric current, time and position, and the effect of annealing processing were investigated experimentally too. With this technique, an in-line distributed feedback fiber laser with 1.16 kHz line-width was made.
