摘要

The gain-flattening filter of an erbium-doped fiber amplifier is experimentally demonstrated by using the technology of etching long-period gratings (LPGs). An error of gain flatness less than 1 dB is obtained by using three cascaded LPGs with different cladding diameters in the range from 1536 to 1565 nm.
