Abstract
ABSTRACT In this paper, we theoretically and experimentally investig ated a two-stage erbium-doped fiber amplifier (EDFA) with a single-pump laser diode pumped at 980 nm in which a Sagnac interferometer filter is introduced to reduce amplified spontaneous emission (ASE) providing significant improvement on the amplifier performance. The erbium-doped fiber (EDF) parameters were measured in order to optimize parameters such as pump power, EDF length, ASE noise and signal gain. The Sagnac interferometer filter was designed to provide a periodic transmittance of 46 nm that allows by temperature to adjust the minimum tran smission at 1530 nm (peak of the ASE noise) and maximum transmission at 1550 nm (signal wavelength). Experimental results show that with a simple configuration we obtained up to 53-dB amplification with only 75 mW of pump power, which can be enhanced easily by 3 dB providing total amplification up to more than 55 dB. Keywords: Erbium-doped fiber Amplifiers, Optical Amplifiers, Erbium.
