Abstract
Based on the plasma chemical vapor deposition (PCVD) process, the Ge/F (Germanium/Fluorine) and Ge/B (Germanium/Boron) co-doped photosensitive fiber was developed. Through analyze the fiber's photosensitivity, study the fiber's photosensitivity influenced by the doping process. The fiber's data indicate that the high F doped (5 mol%) Ge/F photosensitive fiber's grating has the 80% reflectivity, much lower than the low F doped (1 mol%) Ge/F photosensitive fiber's 94% reflectivity. Then the Boron doped would increase the fibre's photosensitivity distinctly just when the dope concentration reach about 5 mol%. Present the experimental study of the influence of doping on fiber photosensitivity. Through measuring the attenuation spectra and comparing the reflectivities of the fabricated fiber Bragg gratings (FBGs), the photosensitivity of GeF and GeB co-doped fibers are investigated.
