Dynamic Characterization of EDFA Based on ASE Selective-feedback and Gain-clamping Techniques

  We experimental demonstrated a gain clamped C-band EDFA with a stable wide dynamic range performance by using the ASE selective-feedback gain-clamping technique.The gain of 16.2 dB with variation ±0.26 dB for the input signal power from-35 to-5dBm and the maximum NF of 6.6 dB for the input signal power from-35 to-10dBm were obtained,respectively.Therefore,a wide dynamic range of the input signal of 25-30 dB can be achieved.We also applied a saturation tone signal(on/off)for simulating the 16-channels DWDM signals(add/drop)to investigate the gain variation for the probe signal.When the number of channel signals are added or dropped in our proposed C-band EDFA scheme,the gain variation is less than 0.13 dB for the signals wavelength range from 1530 to 1564 nm.
