Gain-Clamped L-Band Erbium-Doped Fiber Amplifier with Co- and Counter-Propagating Lasers

The long-wavelength-band (L-band) gain-clamped erbium-doped fiber amplifier with a co- and counter-propagating ring lasers is investigated. The ring laser at 1566nm is formed with a C/L-band wavelength division multiplexing (WDM) coupler. This new technique has shown a good gain-clamping effect with...

The ring laser at 1566nm is formed with a C/L-band wavelength division multiplexing (WDM) coupler. This new technique has shown a good gain-clamping effect with gain variation of less than 0.2 dB for input signal powers from -40 to -14 dBm.
