A highly efficient, low-noise and tunable gain-clamped L-band erbium-doped fiber amplifier is demonstrated using a Fabry-Perot laser in a double-pass system. The broad-band fiber Bragg grating (FBG) operating in the L-band region is used to retro pass the test signal to the system for enhanced gain....
