An efficient EYDFA with a 54 dB small signal gain
An efficient erbium/ytterbium codoped fiber amplifier is demonstrated by using a dual-stage configuration with a midway optical isolator and a band-pass filter (BPF). The amplifier achieved a maximum low signal gain of 54 dB and a corresponding noise figure of 6.5 dB (1536 nm) using the input signal...
