摘要：

A simple experimental method to design gain-flattened erbium-doped fiber amplifier is proposed and demonstrated based on the two linear relations between the output power and the pump power, and between the gain and the length of the erbium-doped fiber at the gain flattened state. The spectral gain variation of the erbium-doped fiber amplifier constructed by this method was less than 0.4 dB over 12 nm (1,545 similar to 1,557 nm) wavelength region. The gain flatness is also controlled within 0.4 dB over the input power range of -30 similar to -15 dBm/ch through the feedback control utilizing the amplified spontaneous emission power in the 1,530 nm region.
