Flat-gain and wideband EDFA by using dual stage amplifier technique

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...
