Paper Abstract

An erbium-doped fiber amplifier (EDFA) gain flattening technique using an embedded long period grating (ELPG) is proposed. By bending the ELPG, because the different bending curvature yields the different coupling strength, it is used for the dynamic gain flattening despite the different pump power on the EDFA. The flattened gain region of 35nm can be achieved with 1dB ripple.
