The partial double-pass L-band erbium-doped fiber amplifier with enhanced gain characteristic is demonstrated using a band pass filter (BPF). The BPF is incorporated to the doublepass route to suppress the amplified spontaneous emission from the single-pass output for gain enhancing. The gain of 515...
