Abstract
Gain-clamped double-pass (GC-DP) long-wavelength band (L-band) erbium-doped fiber amplifier (EDFA) is demonstrated with enhanced gain characteristics by placing an optical circulator at the output end of an erbium-doped fiber. Compared to previous gain-clamped single pass EDFA, the proposed GC-DP EDFA provides a gain enhancement of more than 3.5 dB for all tested wavelengths except 1560 nm, at the expense of noise figure.
