Abstract

In this paper, the flat-gain and wideband amplification of erbium-doped fiber amplifier (EDFA) was demonstrated by using a dual stage amplifier technique. The performance of dual stage amplifiers was investigated at high (- 10 dBm) and low (-30 dBm) input signal powers and then compared with that of single stage amplifier performance in terms of varying length of the gain medium, pump power and input signal power. Both stages of amplifiers showed better amplification performance at low input signal power of -30 dBm, as compared to high input signal power of -10 dBm. The dual stage amplifier showed better amplification for all experiments in comparison with the single stage amplifier. The dual stage amplifier gave the highest gain from the gain medium the of 2 m and 20 m for EDF1 and EDF2, respectively, with the highest pump power of 700 mW. Succinctly, through the dual stage amplifier technique, flat-gain and wideband EDFA were significantly achieved.
