Efficient and low-noise gain-flattened double-pass L-band erbium-doped fiber amplifier
A new double-pass long-wavelength-band erbium-doped fiber amplifier with enhanced noise figure characteristics is demonstrated by adding a short length of forward pumped erbium-doped fiber (EDF) in front of the double-pass amplifier. By adding 7 m of EDF, the amplifier achieves a flat-gain output at...
