Abstract
We report on a parametric study to optimize the Er3+-doped fiber amplifiers performances. A 24 dB efficient gain in Er3+- doped silica-based fibers has been achieved for small signal regime at 1.553 μm with a 40 mW pump power in the 1.48-1.49 μm range. The saturation output signal power was up to 20 mW for a gain of 17 dB. For the signal wavelength a 3dB-bandwidth of 30 nm has been obtained always with a pump around 1.48 4m. We achieved these results by optimizing the relevant parameters which are the pump and signal characteristics (wavelength and power), the Er3±-concentration and length for the doped fiber. We report on the main parameters which determine the amplifier efficiency (gain, saturation output power, saturation gain, bandwidth, amplified spontaneous emission,...). It is worth noticing that an outstanding amplification is obtained at 1.55 μm wavelength where the gain value is not optimal in order to demonstrate the capability of such amplifiers.
