Abstract

Using a new numerical model, the pump-to-signal relative intensity noise (RIN) transfer in singlepump
fiber optical parametric amplifiers for low modulation frequencies is investigated. The model includes
fiber loss, pump depletion, as well as the gain saturation, and therefore, it can describe the practical
circumstances associated with various applications of fiber optical parametric amplifiers. The nonlinear
dynamics of the RIN transfer for different pump and signal powers is studied. The impact of the input pump
and signal powers and signal wavelength on the RIN transfer is also investigated. Finally, the model is
compared to the available experimental data and a very good agreement is obtained
