A NEW NUMERICAL MODEL FOR THE PUMP-TO-SIGNAL RIN TRANSFER IN SINGLE-PUMP FIBER OPTICAL PARAMETRIC AMPLIFIERS

Abstract

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