Abstract

The principle of a novel gain grating method, which enables an on-line monitoring of the Bragg wavelengths of fiber gratings (FG's) to be formed in Er-doped fibers (EDF's), is experimentally confirmed. The 532nm second harmonic of a mode-locked Nd: YAG laser is used as a writing light source in this experiment. Firstly, it is observed that the 532nm light can induce a refractive index change in EDF's which is enough for FG formations. Secondly, the formation of gain gratings in EDF's is confirmed, and a wavelength controllability better than 0.2nm is expected.
