摘要：

The characteristics of an apodized long-period grating are studied experimentally mud theoretically,. It has no side-lobes and almost zero insertion loss in the pass band. Changing the do and maximum ac index along the z direction of LPG can conveniently control wavelength and the value of peak loss. Suitable spectral profile of gain-flattening filter with low insertion loss is obtained by writing two or three consecutive apodized sub-gratings in one fiber with the different UV power level in the second exposure. The experiment results are in good agreement with the simulation results. (C) 2002 Wiley Periodicals.
